DESCRIPTION
The MS6266 is a 6-channel volume controller IC with gain and attenuation. It uses CMOS technology specially for the
low voltage application with low noise, rail-to-rail output. The MS6266 provide an I²C control interface with gain /
attenuation range of 16dB to -79dB, 1dB/step. The initial condition is set to be maximum attenuation –79dB and mute
on mode when the power is on.
