Features 7-band graphic equalizer for one channel can be formed

easily by externally connecting capacitors and variableresistors which fix fo (resonance frequency).

Series connection of the LA3607 makes multiband avail-able.

Boost, cut amount can be varied by external resistors. Highly stable to capacitive load.

fo (resonance frequency)In the sample application circuit, fo for each of 7 bands is set as follows :

fo=60Hz, 150Hz, 400Hz, 1kHz, 2.5kHz, 6kHz, 15kHzfo is calculated using the following formula.

fo=

Q (quality factor)Q is calculated using the following formula.

When Q is increased, the frequency band affected by the resonance circuit is narrowed and a clear distinction be-tween this band and adjacent band is provided, but the frequency response swells greatly at all boost mode and thepeak of the composite frequency is lowered. The above must be considered to fix C1, C2.

Description of external partsC1, C2 : Capacitors used to fix fo (resonance frequency)C3 : Input capacitor. Decreasing the capacitor value lowers the frequency response at low frequencies.C4 : Decoupling capacitor. Decreasing the capacitor value makes the effect of power supply stronger, whereby

repple is liable to occur.C5 : Power capacitor.C6 : Putput capacitor. Decreasing the capacitor value lowers the frequency response at low frequencies.

Proper cares in using IC Maximum supply voltage VCC max 20V must not be exceeded. The operating voltage is in the range of 5 to 15V. Application of power with the pin-to-pin spaces shorted causes breakdown or deterioration of the IC to occur.

When mounting the IC on the board of applying power, make sure that the pin-to-pin spaces are not shorted withsolder, etc.
