2-CH ELECTRONIC VOLUME CONTROLLER WITH LOUDNESS CONTROL
DESCRIPTION
The SC9235 is an optimum
CMOS IC which has been designed for electronization of volume control of audio equipment, etc.
FEATURES
* Attenuation can be controlled from 0dB to -78dB by up, down input.
* This IC have 20dB tap for loudness circuit. * This IC features a built-in DC output circuit (7 level) for volume
level meter. * Polysilicon resistors enables low-distortion, high-performance
volume systems. * Volume level remains in backup mode with low current
consumption. * Package is DIP16 and SOP16.
