BA3313L中文资料罗姆数据手册PDF规格书

The BA3313L is a dual preamplifier IC with built-in ALC detector circuit, designed for use in stereo radio cassette recorders. It comes in a compact 12-pin ZIP package, and has two record/playback preamplifiers, and an ALC detector circuit.

The preamplifiers can be directly coupled to the tape head without coupling capacitors to prevent tape head magnetization and “pop” noise generation.

With the built-in ALC detector circuit, an ALC circuit with large dynamic range can be constructed with addition of just an external time constant circuit.
