UTC BA3308


DUAL PREAMPLIFIER WITH ALC
LINEAR INTEGRATED CIRCUIT
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
(V_CC =6.0V ~ 14V)
* Power-on mute circuit to avoid “pop” noise generation.
* No input coupling capacitors are necessary
* High gain (G_VO=80dB)and low noise (V_NIN=1µVrms)
* Low distortion (THD=0.1%)
* Good ALC channel balance with built-in ALC rectifier diode
* Adjustable ALC dynamic range by external input resistor.
