The TDA7801PDTR 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 TDA7801PDTR a very flexible machine.
