DESCRIPTION
The MS6260 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 MS6260 provide an I
2
C control interface with gain / attenuation
range of 15dB to –79dB, 1dB/step. The excellent power supply ripple reject is a good for audio system. The initial
condition is set to be maximum attenuation –79dB and mute on mode when power on.
