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 * Minimum number of external parts required
