SC9260
2-CH ELECTRONIC VOLUME CONTROLLER CONTROLLED BY SERIAL
INTERFACE WITH LOUDNESS CONTROL
DESCRIPTION
The SC9260 and SC9260S are an optimum CMOS with I2C interface
on Chip, which has been designed for electrification of volume control
of audio equipment, etc.
FEATURES
DIP-16-300-2.54
* Attenuation can be controlled from 0dB to -78dB by 2dB/step.
* This ICs feature a built-180in loudness circuit.(20dB tap)
* The volume, balance and loudness circuits can be controlled by I2C
series data.
SOP-16-300-1.27
* CS (Chip Select) input allows control of up to 2 of this chip on the
same bus.
* Use Polysilicon resistors enable low-distortion, high-performance
volume system.
