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=0.1%)
* Good ALC channel balance with built-in ALC rectifier diode
* Adjustable ALC dynamic range by external input resistor. |
