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
