Description
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.
