TEA6430

TEA6430 AUDIO CELLULAR MATRIX . . . . . . . 5 STEREO INPUTS - 4 STEREO OUTPUTS 3-STATE OPERATION FOR EACH OUTPUT GAIN OUTPUT CONTROL 0dB/2/4/6dB/MUTE FOR EACH VERY LOW NOISE AND DISTORTION I2C BUS CONTROL 4 SUB-ADDRESS FACILITY 90dB CROSSTALK BETWEEN ANY INPUT AND OUTPUT DESCRIPTION The TEA6430 switches 5 stereo inputs on 4 stereo outputs, providing the customer with high quality sound (low noise, low distortion). The 4 stereo outputs can be set separately in high impedance state, to enable parallel connection of several devices (up to 4). All functions are controlled through the I2C bus.
