DESCRIPTION

The wPC1228, a silicon monolithic integrated circuit, is a low noise dual preamplifier designed for car stereo applications. The device consists of two separate amplification channels, and its major features are low noise, low distortion, high gain, large dynamic range and wide supply voltage range.

FEATURES

© High open loop gain > Ayo = 100 dB TYP. © Low noise Vain = 1.1 uv TYP. ®@ Low distortion : THD=0.05 % TYP. © Large dynamic range : Vom =2.0 V TYP. © Wide supply voltage range : Veco =6 to 16 V @ High output current : lope= 1mA MAX. @ Low impedance load driving capability >RyL=1kQ MIN @ Small feedback capacitance capability
