6-CH ELECTRONIC VOLUME CONTROLLER
DESCRIPTION
SC5358 is a 6-channel electronic volume controller IC mainly designed
for the current multi-channel AV systems. It provides an I2C control
interface, a selectable address and an attenuation range from 0 to –
79dB at 1dB/step.
FEATURES
* CMOS technology
* I2C bus control interface
* Selectable address
* Attenuation range: 0~-79dB(1dB/step)
* Power supply: 5~9V
* S/N>100dB
* High Channel Separation
APPLICATIONS
* 5.1-channel AV system
* Computer multi-media system
* Other multi-channel systems

SC5358
When adjusting the volume of a channel both a 10dB code and a 1dB code must be send just as follows.
Example The setting of Channel 5 is -36dB.
