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
