descriptionThe TLV277x CMOS operational amplifier family combines high slew rate and bandwidth, rail-to-rail outputswing, high output drive, and excellent dc precision. The device provides 10.5 V/s of slew rate and 5.1 MHzof bandwidth while only consuming 1 mA of supply current per channel. This ac performance is much higherthan current competitive CMOS amplifiers. The rail-to-rail output swing and high output drive make thesedevices a good choice for driving the analog input or reference of analog-to-digital converters. These devicesalso have low distortion while driving a 600- load for use in telecom systems.These amplifiers have a 360-V input offset voltage, a 17 nV/Hz input noise voltage, and a 2-pA input biascurrent for measurement, medical, and industrial applications. The TLV277x family is also specified across anextended temperature range (40C to 125C), making it useful for automotive systems, and the militarytemperature range (55C to 125C), for military systems.These devices operate from a 2.5-V to 5.5-V single supply voltage and are characterized at 2.7 V and 5 V. Thesingle-supply operation and low power consumption make these devices a good solution for portableapplications. The following table lists the packages available.

driving a capacitive loadWhen the amplifier is configured in this manner, capacitive loading directly on the output will decrease thedevices phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greaterthan 10 pF, it is recommended that a resistor be placed in series (RNULL) with the output of the amplifier, asshown in Figure 58. A minimum value of 20 should work well for most applications.

general configurationsWhen receiving low-level signals, limiting the bandwidth of the incoming signals into the system is oftenrequired. The simplest way to accomplish this is to place an RC filter at the noninverting terminal of the amplifier(see Figure 60).

If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter can be used for thistask. For best results, the amplifier should have a bandwidth that is 8 to 10 times the filter frequency bandwidth.Failure to do this can result in phase shift of the amplifier.

using the TLV2772 as an accelerometer interfaceThe schematic, shown in Figure 62, shows the ACH04-08-05 interfaced to the TLV1544 10-bit analog-to-digitalconverter (ADC).The ACH04-08-05 is a shock sensor designed to convert mechanical acceleration into electrical signals. Thesensor contains three piezoelectric sensing elements oriented to simultaneously measure acceleration in threeorthogonal, linear axes (x, y, z). The operating frequency is 0.5 Hz to 5 kHz. The output is buffered with aninternal JFET and has a typical output voltage of 1.80 mV/g for the x and y axis and 1.35 mV/g for the z axis.Amplification and frequency shaping of the shock sensor output is done by the TLV2772 rail-to-rail operationalamplifier. The TLV2772 is ideal for this application as it offers high input impedance, good slew rate, andexcellent dc precision. The rail-to-rail output swing and high output drive are perfect for driving the analog inputof the TLV1544 ADC.

The sensor signal must be amplified and frequency-shaped to provide a signal the ADC can properly convertinto the digital domain. Figure 62 shows the topology used in this application for one axis of the sensor. Thissystem is powered from a single 3-V supply. Configuring the TLV431 with a 2.2-k resistor produces a referencevoltage of 1.23 V. This voltage is used to bias the operational amplifier and the internal JFETs in the shocksensor.

gain calculationSince the TLV2772 is capable of rail-to-rail output using a 3-V supply, VO = 0 (min) to 3 V (max). With no signalfrom the sensor, nominal VO = reference voltage = 1.23 V. Therefore, the maximum negative swing from nominalis 0 V 1.23 V = 1.23 V and the maximum positive swing is 3 V 1.23 V = 1.77 V. By modeling the shock sensoras a low impedance voltage source with output of 2.25 mV/g (max) in the x and y axis and 1.70 mV/g (max) inthe z axis, the gain of the circuit is calculated by equation 1.

Gain Output SwingSensor Signal Acceleration (1)

To avoid saturation of the operational amplifier, the gain calculations are based on the maximum negative swingof 1.23 V and the maximum sensor output of 2.25 mV/g (x and y axis) and 1.70 mV/g (z axis).

Gain (x, y) 1.23 V2.25 mVg 50 g 10.9 (2)

Gain (z) 1.23 V1.70 mVg 50 g 14.5 (3)and

By selecting R3 = 10 k and R4 = 100 k, in the x and y channels, a gain of 11 is realized. By selectingR3 = 7.5 k and R4 = 100 k, in the z channel, a gain of 14.3 is realized. The schematic shows the configurationfor either the x- or y-axis.

bandwidth calculationTo calculate the component values for the frequency shaping characteristics of the signal conditioning circuit,1 Hz and 500 Hz are selected as the minimum required 3-dB bandwidth.To minimize the value of the input capacitor (C1) required to set the lower cutoff frequency requires a large valueresistor for R2 is required. A 1-M resistor is used in this example. To set the lower cutoff frequency, the requiredcapacitor value for C1 is:

C1 12 fLOW R2 0.159 F (4)

Using a value of 0.22 F, a more common value of capacitor, the lower cutoff frequency is 0.724 Hz.To minimize the phase shift in the feedback loop caused by the input capacitance of the TLV2772, it is best tominimize the value of the feedback resistor R4. However, to reduce the required capacitance in the feedbackloop a large value for R4 is required. Therefore, a compromise for the value of R4 must be made. In this circuit,a value of 100 k has been selected. To set the upper cutoff frequency, the required capacitor value for C2 is:

C2 12 fHIGH R4 3.18 F (5)

Using a 2.2-nF capacitor, the upper cutoff frequency is 724 Hz.R5 and C3 also cause the signal response to roll off. Therefore, it is beneficial to design this roll-off point to beginat the upper cutoff frequency. Assuming a value of 1 k for R5, the value for C3 is calculated to be 0.22 F.

circuit layout considerationsTo achieve the levels of high performance of the TLV277x, follow proper printed-circuit board design techniques.A general set of guidelines is given in the following. Ground planesIt is highly recommended that a ground plane be used on the board to provide all

components with a low inductive ground connection. However, in the areas of the amplifier inputs andoutput, the ground plane can be removed to minimize the stray capacitance.

Proper power supply decouplingUse a 6.8-F tantalum capacitor in parallel with a 0.1-F ceramiccapacitor on each supply terminal. It may be possible to share the tantalum among several amplifiersdepending on the application, but a 0.1-F ceramic capacitor should always be used on the supply terminalof every amplifier. In addition, the 0.1-F capacitor should be placed as close as possible to the supplyterminal. As this distance increases, the inductance in the connecting trace makes the capacitor lesseffective. The designer should strive for distances of less than 0.1 inches between the device powerterminals and the ceramic capacitors.

SocketsSockets can be used but are not recommended. The additional lead inductance in the socket pinswill often lead to stability problems. Surface-mount packages soldered directly to the printed-circuit boardis the best implementation.

Short trace runs/compact part placementsOptimum high performance is achieved when stray seriesinductance has been minimized. To realize this, the circuit layout should be made as compact as possible,thereby minimizing the length of all trace runs. Particular attention should be paid to the inverting input ofthe amplifier. Its length should be kept as short as possible. This will help to minimize stray capacitance atthe input of the amplifier.

Surface-mount passive componentsUsing surface-mount passive components is recommended for highperformance amplifier circuits for several reasons. First, because of the extremely low lead inductance ofsurface-mount components, the problem with stray series inductance is greatly reduced. Second, the smallsize of surface-mount components naturally leads to a more compact layout thereby minimizing both strayinductance and capacitance. If leaded components are used, it is recommended that the lead lengths bekept as short as possible.

shutdown function

Three members of the TLV277x family (TLV2770/3/5) have a shutdown terminal for conserving battery life inportable applications. When the shutdown terminal is tied low, the supply current is reduced to 0.8 A/channel,the amplifier is disabled, and the outputs are placed in a high impedance mode. To enable the amplifier, theshutdown terminal can either be left floating or pulled high. When the shutdown terminal is left floating, careneeds to be taken to ensure that parasitic leakage current at the shutdown terminal does not inadvertently placethe operational amplifier into shutdown. The shutdown terminal threshold is always referenced to VDD/2.Therefore, when operating the device with split supply voltages (e.g. 2.5 V), the shutdown terminal needs tobe pulled to VDD (not GND) to disable the operational amplifier.The amplifiers output with a shutdown pulse is shown in Figures 48, 49, and 50. The amplifier is powered witha single 5-V supply and configured as a noninverting configuration with a gain of 5. The amplifier turnon andturnoff times are measured from the 50% point of the shutdown pulse to the 50% point of the output waveform.The times for the single, dual, and quad are listed in the data tables. The bump on the rising edge of the TLV2770output waveform is due to the start-up circuit on the bias generator. For the dual and quad (TLV2773/5), thisbump is attributed to the bias generators start-up circuit as well as the crosstalk between the other channel(s),which are in shutdown.Figures 55 and 56 show the amplifiers forward and reverse isolation in shutdown. The operational amplifier ispowered by 1.35-V supplies and configured as a voltage follower (AV = 1). The isolation performance is plottedacross frequency for both 0.1 VPP and 2.7 VPP input signals. During normal operation, the amplifier would notbe able to handle a 2.7-VPP input signal with a supply voltage of 1.35 V since it exceeds the common-modeinput voltage range (VICR). However, this curve illustrates that the amplifier remains in shutdown even undera worst case scenario.
