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 16d B to -79d B, 1d B/step. The initial condition is set to be maximum attenuation - 79d B and mute on mode when the power is on.
