BA3308
LINEAR INTEGRATED CIRCUIT
DUAL PREAMPLIFIER WITH ALC
DESCRIPTION
The UTC BA3308 is designed to have dual preamplifier ICs with built – in ALC circuits for use in stereo amplification. The preamplifiers have high gain and low distortion. A built-in rectifier for ALC circuit implies good channel balance and large dynamic range can be constructed with addition of just an external time constant circuit.
FEATURES
* Wide operating power supply voltage range (VCC =4.5V ~ 14V)
* Power-on mute circuit to avoid “pop” noise generation. * No input coupling capacitors are necessary * High gain (GVO=80dB)and low noise (VNIN=1µVrms) * Low distortion (THD=0.
