SC9153
2-CH ELECTRONIC VOLUME CONTROLLER
DESCRIPTION
The SC9153 is CMOS IC which has been designed for electronization
volume control of audio equipment,etc.
FEATURES
* Wide operating voltage range(VDD=6V ~ 12V)
www.DataSheet4U.com
* 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.
