ET2354 - 4 stereo inputs/2-channel outputs digital control audio processor

General Description

The ET2354 is a 4 stereo inputs/2­channel outputs digital control audio processor for the low voltage operation.

Volume, tone(bass   treble),  balance(left/right) processor are incorporated into a single chip.

The ET2354 also has the loudness function   & selectable input gain.

Key Features

  • Operation range: 2.7V~5V 4 stereo inputs with selectable input gain 2 independent speaker controls for balance Tone controls (treble & bass) Loudness & independent mute function Volume control in 1.25dB/step I2C interface Components less & good PSRR Housed in SOP28,TSSOP28(ET2354V) package.

General Description The ET2354 is a 4 stereo inputs/2­channel outputs digital control audio processor for the low voltage operation. Volume, tone(bass   treble),  balance(left/right) processor are incorporated into a single chip. The ET2354 also has the loudness function   & selectable input gain. These functions can be built a Hi­Fi 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 & the gains of the input stage, the bass & the treble are 0dB. Features Operation range: 2.
