Low Gain Application Example for 1nV/Hz Amplifier

16Bit 10MHz ADC with 2V swing ½ LSB Noise=10uV 10uV@10MHz=3.4 nV/rt Hz RTO for ADC < 3.4 nV/rt Hz

AD8099 with 1V Input signal G=2 RTO Noise~ 3nV/rt Hz

Competition Low Gain Stable Amplifiers-

Slew Rate is too slow High Gain Stable Amplifiers-

AD8099: Overview of Major Benefits

Enables high-speed, 16-18 bit accurate signal processing provides extra room in the error budget

Allows for use of less expensive components

less calibration/trimming

Application flexibility with wide range of gain stability designer has the advantage of low noise at low gains with high slew rate

easy to reuse in other designs

Shorter time to market, less risk and lower cost easier to lay out

less thermal modeling

lower heat budget 3mA lower quiescent current than its leading competitors
