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

control the configuration and behavior of the

a very flexible machine.
