UTC KA22241 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.
SIP-9
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
