MS6712 Datasheet | MOSA

MOSA 4 Stereo Inputs / 4-Channel Outputs Audio Processor 4 Stereo Inputs and 4-Channel Outputs Volume, Tone, Balance, Fader, Loudness, and Selectable Input Gain Features - Operation range : 2.7V~6.5V - 4 stereo inputs with selectable input gain - 4 independent speaker controls for fader and balance - Tone controls (treble and bass) and loudness function - Independent mute function - Volume control in 1.25 d B/step - I2C interface - ponents less and good PSRR - Housed in SOP32 packages APPLICATIONS - Portable audio device - Car stereo audio - Hi-Fi audio system DESCRIPTION The MS6712 is a 4 stereo inputs/4-channel outputs digital control audio processor for the low voltage operation. Volume, tone (bass and treble), balance (left/right), and fader (front/rear) processor are incorporated into a single chip. The MS6712 also has the loudness function and selectable input gain. These functions can be built a Hi-Fi audio system easily. All functions are programmable via the serial I2C bus. The default states of the chip as the power is on are: the volume is -78.75d B, the stereo 4 is selected, all the speakers are mute and the gains of the input stage, the bass and the treble are 0d B.
