www.DataSheet4U.com MOSA MS6260 Gain And Attenuation Volume Controller IC Gain and Attenuation Volume Controller IC One Set of Stereo Input, Low voltage Gain and Attenuation 15~-79dB, Good PSRR FEATURES ‧Operation range: 2.7V~5.5V ‧Low power consumption ‧Gain/Attenuation: 15dB to –79dB at 1dB/step ‧Good PSRR and low pop noise ‧Housed in 10 pin MSOP package ‧I2C interface APPLICATIONS ‧Multimedia system ‧Hi-Fi audio system ‧MP3, PDA 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 I2C 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. PIN CONFIGURATION Symbol A.O.
