DESCRIPTION

The SC9153A is CMOS IC which has been designed for electronization volume control of audio equipment,etc.

FEATURES

*Wide operating voltage range(VDD=6V ~ 12V)

*Low current comsumption .

*Attenuation can be controlled from 0dB to –66dB by 2dB/step

*Both of dual power suppliers of (+) and (-) and a single power supply can be used.

*Be capable of controlling attenuation by means of the built-in oscillator and the up/down terminals.
