Preamps with Built-in ALC - BA3308F

The BA3308F/FV is a dual preamplifier for recording and playback with ALC (auto level control), developed for stereo radio,cassette recorders, tape recorders, and other pre amplifiers audio applications.
ALC circuit has a build in rectification circuit with wide adjustable dynamic range, high gain, low distortion amplifiers withdirect coupling and mute circuit, used to cut off pop noise during power on.
Available in SOP14, or SSOP-B14 Packages.
