BA3308 Dual preamplifier

Audio ICs 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 preamplifiers, and an ALC circuit. The preamplifiers have high gain and low distortion, and can be directly coupled to the tape head.
