5 BAND DUAL GRAPHIC EQ AMP
S1A0234B01
INTRODUCTION
The S1A0234B01 is a monolithic integrated circuit developed
for the tereo 5 band graphic equalizer amplifier.
It consists of an operational amplifier, and four resonant circuits
with an active filter. It is suitable for radio cassette-tape record-
ers, car stereos or music centers.
24−SZIP−275
FEATURES
• Tone control with independent adjustment of each band through
external capacitor
• Gain control through external variable resistor (Gain = ±11dB)
• Excellent cross talk characteristics (CT = 70dB Typ, at R_G = 0)
• Wide operating supply voltage range: V_CC = 3.5V — 14V
