Dual preamplifier with ALC
BA3308 / BA3308F / BA3308FV
The BA3308, BA3308F and BA3308FV are dual preamplifier ICs with built-in ALC circuits, and have been designed for use in stereo radio-cassette recorders and tape recorders.
They come in compact 9-pin SIP (BA3308), 14-pin MF (BA3308F) and 14-pin SSOP (BS3308FV) packages, and have two record / playback pre
amplifiers, and an ALC circuit.
The pre
amplifiers 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.
A built-in rectifier means that an ALC circuit with good channel balance and large dynamic range can be ...
