TDA7801 Digital input (I2S) quad BTL output with full I²C diagnostics

The TDA7801 is a new BCD technology quad bridge amplifier for car audio applications.

Thanks to the BCD6 technology it is possible to integrate a high performance D/A converter together with powerful MOSFET outputs.

The possibility of having the D/A conversion on board allows the performance to reach an outstanding 115 dB S/N ratio with more than 105 dB of dynamic range.

This device is equipped with a full diagnostics array that communicates the status of each speaker through the I²C bus. The possibility to control the configuration and behavior of the device by means of the I²C bus makes TDA7801 a very flexible machine.
