DESCRIPTION
The MS6274 is a stereo audio volume controller IC with 4 sets of stereo inputs(1 quasi-differential Input). It has
Input gain(0 ~ +15dB), Soft step volume control(-79dB ~ +15dB) with programmable blend times. It uses CMOS
technology specially for the low voltage application with low noise, rail-to-rail output.
