Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Applications
• Portable component stereos, tape-recorders, radio-cassette
recorders, car stereos.
Features
• On-chip one operational amplifier.
• 5-band graphic equalizer for one channel can be formed
easily by externally connecting capacitors and variable
resistors which fix fo (resonance frequency).
• Series connection of two LA3600’s makes multiband (6
to 10 bands) available.
• Highly stable to capacitive load.

Sample Application Circuit
LA3600
fo (resonance frequency)
In the sample application circuit, fo for each of 5 bands is set as follows :
fo=108Hz, 343kHz, 1.08kHz, 3.43kHz, 10.8kHz
fo= (R1=1.2kΩ, R2=68kΩ on-chip resistor)
2π √ C1, C2, R1, R2
Description of external parts
C1, C2 : Capacitors used to fix fo (resonance frequency)
C2 : Input capacitor. Decreasing the capacitor value lowers the frequency response at low frequencies.
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
ripple is liable to occur.
C5 : Power capacitor.
C6 : Output 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 or applying power, make sure that the pin-to-pin spaces are not shorted with
solder, etc.
