DESCRIPTION
The MS6258 is a stereo audio volume controller IC with 4 sets of stereo input. It uses CMOS technology specially for
the low voltage application with low noise, rail-to-rail output. The MS6258 provide an I
2
C 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 on.
