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 I
control the configuration and behavior of the
device by means of the I
a very flexible machine.
