MS6714_1

MOSA MS6714 4 Stereo Inputs / 1 Stereo Output Audio Processor 4 Stereo Inputs and 1 Stereo Output Volume, Tone, Balance, Loudness and Selectable Input Gain FEATURES •Operation range : 2.7V~6.5V •4 stereo inputs with selectable input gain •2 independent speaker controls for balance •Tone controls (treble and bass) •Loudness and independent mute function •Volume control in 1.25 dB/step •I2C interface •Components less and good PSRR •Housed in SOP28, SSOP28 package APPLICATIONS •Portable audio device •Car stereo audio •Hi-Fi audio system DESCRIPTION The MS6714 is a 4 stereo inputs/2-channel outputs digital control audio processor for the low voltage operation. Volume, tone (bass and treble), and balance (left/right) processor are incorporated into a single chip. The MS6714 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 -78.75dB, the stereo 4 is selected, all the speakers are mute and the gains of the input stage, the bass and the treble are 0dB.
