ELECTRONIC VOLUME
DESCRIPTION
The SC9235 and SC9235S are an optimum CMOS IC which
has been designed for electronization of volume control of audio
equipment, etc.
SOP-16
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.
