INTRODUCTION
The KA2223 is a monolithic integrated Circuit consisting of an operational amplifier with five resonant Circuits and a active filter, and it is suitable for radio-cassette tape recorder, car stereo or
music center audio systems.

FEATURES
· Tone control with independent adjustment of each band through an external capacitor.
· Gain control through an external variable resistor.
· Increasing the bands by adding resonant circuit or using two KA2223 in series.
· Low noise (VNO= 7mV: Typ. Flat).
· Low distortion (THD = 0.02% Typ. f = lKHz Flat).
· Large input allowance (VI= 2.3V: Typ, V CC= 9V, f =1KHz Flat).
· Operating Supply voltage range: V CC= 5V ~ 13V
