UNISONIC TECHNOLOGIES CO., LTD BA3308 Preliminary LINEAR INTEGRATED CIRCUIT w w w . u n i s o n i c . c o m . t w 1 of 4 Copyright © 2011 Unisonic Technologies Co., Ltd QW-R107-015.Ba 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 lo w distortion. A built-in rectifier for ALC circuit implies good channel balance and large dynamic range can be constructed with additi on 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 (G VO=80dB)and low noise (VNIN=1µVrms) * Low distortion (THD=0.1%) * Good ALC channel balance with built-in ALC rectifier diode * Adjustable ALC dynamic range by external input resistor.
