KA2224B
DUAL EQ AMP WITH ALC
GENERAL DESCRIPTION
The KA2224B is a monolithic integrated circuit consisting of a dual
equalizer amplifier with ALC, and it is suitable for stereo radio
cassettes.
FEATURES
Dual equalizer amplifier with a built-in ALC circuit.
Recording amp available because of high gain characteristic
(Variable monitor possible).
Good channel separation (CS = 50dB Typ).
Quick stabilization after power on.
Capable of direct meter driving and ALC transistor.
Good ALC response balance between channels.
Wide operating supply voltage range: V =4V ~ 13V
