BA3311L Dual preamplifier with ALC

Audio ICs Dual preamplifier with ALC BA3311L The BA3311L is a dual preamplifier with ALC 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 circuit. The preamplifiers are directly coupled to the head and do not require coupling capacitors. This prevents tape h.

Features

1) The input block uses a bias circuit that does not require coupling capacitors. 2) ALC circuit requires addition of just an external detector and time constant circuit.
