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.
