DESCRIPTION

The MS6257 is the stereo audio volume controller IC. It uses CMOS technology specially for the low voltage application with low noise, rail-to-rail output. The MS6257 provide an I2C control interface with gain / attenuation range of 15dB to –79dB, 1dB/step. The initial condition is set to be maximum attenuation –79dB and mute on mode when the power is up.
