5 BAND Audio GRAPHIC EQUALIZER AMPLIFIER using KA2223
The KA2223 is a monolithic integrated circuit consisting of an operational amplifier with five resonant circuits and a active filter, an it is suitable for radio-cassette tape recorders, car stereos 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=7uV:Typ.Flat).
Low distortion (THD=0.02% Typ.f=1KHz Flat).
Large allowable input (Vl= 2.3V :Typ,Vcc= 9V,f= 1KHz flat).
Operating supply voltage range: Vcc= 5V – 13V
