5 BAND GRAPHIC EQ AMP
S1A2223X
1
INTRODUCTION
The S1A2223X is a monolithic integrated Circuit consisting of
an operational amplifier with five resonant circuits and an active
filter. It is suitable for radio-cassette tape recorders, car stereos
and audio systems.
FEATURES
Tone control with independent adjustment of each band through
an external capacitor
Gain control through an external variable resistor
