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 I2C control interface with gain / attenuation range of 15dB to -79dB. The gain and attenuation, +1dB/step, -1dB/step and -10dB/step are controlled independently. The initial condition is set to be maximum attenuation –79dB (-70dB + -9dB), gain 0dB and mute on mode when the power is up.

FEATURES
• Operation range: 2.7V~6.5V.
• Low power consumption.
• Gain/Attenuation: 15dB to –79dB.
• +1dB/step, -1dB/step and -10dB/step are controlled independently.
• Good PSRR and low pop noise.
• I2C interface.
• Housed in 16 pin SOP, SSOP package.

APPLICATIONS
• Multimedia system.
• Hi-Fi audio system.
• MP3， PDA.
