Dual preamplifier with ALC

BA3306

The BA3306 is a dual preamplifier with ALC designed for use in stereo radio-cassette recorders and tape recorders. It

comes in a compact 9-pin SIP package and has two record / playback preamplifiers, and an ALC circuit. The preamplifi-

ers have high gain and low distortion, and can be directly coupled to the tape head without coupling capacitors. This

prevents tape head magnetization and “pop” noise generation.

The ALC circuit has good channel balance and large dynamic range and can be constructed with addition of just an exter-

nal detector and time constant circuit.

The IC also includes a power-on mute circuit that suppresses “pop” noise generation.

FApplications

Stereo radio cassette players

FFeatures

1) Wide operating power supply voltage range

= 4.5V to 14V).

2) Low current dissipation (I

= 2.5mA).

3) High gain (G

= 80dB).

4) Low distortion (THD = 0.1%).
