BA3308F - Rohm

BA3308F Preamps

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 with direct coupling and mute cir.

Features

1) Built-in ALC rectification diode 2) Wide operating power supply voltage range (VCC=4.5~14 V) 3) Low current consumption (IQ=3.5mA) 4) High gain (GVO=80dB) 5) Low distortion (THD=0.1%) 6) Low noise (VNIN=1 μVrms) 7) Input coupling capacitor not needed 8) Good ALC channel balance 9) Built-in power supply mute circuit 10) Dynamic range of ALC can be changed by attaching input resistance.
