TEA6420 is a bus-controlled audio matrix switch chip with 5 stereo inputs and 4 stereo outputs. All the switching possibilities are changed through the I2C bus. It has gain control of 0/2/4/6dB/mute for each output, can be cascaded (2 different addresses), and is controlled via serial bus. It has very low noise and distortion.
The TEA6420 is a bus-controlled audio matrix switcher designed to switch 5 stereo audio inputs to 4 stereo outputs. It features gain control (0/2/4/6dB) and mute functions for each output, as well as cascading capabilities via two different addresses. The device is controlled entirely through an I2C serial bus.
