MOSA GAIN AND ATTENUATION VOLUME CONTROLLER IC Gain and Attenuation Volume Controller IC One Set of Stereo Input, Low voltage Gain and Attenuation 15~-79d B Features ‧Operation range: 2.7V~5.5V ‧Low power consumption ‧Gain/Attenuation: 15d B to - 79d B at 1d B/step ‧Housed in 8 pin SOP package ‧I2C interface APPLICATIONS ‧Multimedia system ‧Hi-Fi audio system ‧MP3, PDA ‧Cross-reference PT2257, PT2259 DESCRIPTION The MS6257 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 MS6257 provide an I2C control interface with gain / attenuation range of 15d 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 up.
