LINEAR INTEGRATED CIRCUIT  
DUAL EQUALIZER AMPLIFIER  
WITH ALC  
„
DESCRIPTION  
The UTC KA22241 is a monolithic integrated circuit, consisting  
of dual equalizer amplifier with ALC, and it is suitable for stereo  
radio cassette tape recorders.  
„
FEATURES  
* Dual equalizer amplifier with built-in ALC circuit  
* Low noise VNI=1.0μV(Typical)  
* High open loop voltage gain: Gv=80dB(Typical)  
* Good ALC response balance between channels  
* Not necessary the input coupling capacitor  
* Not necessary the diode or transistor for ALC  
* Built in power supply muting circuit  
Lead-free:  
Halogen-free: KA22241G  
KA22241L  
* Minimum number of external parts required
