– Independent front/rear soft play/ mute

– Selectable gain (four levels) for very low

noise line-out function

Description

– I C bus digital diagnostics (including DC

and AC load detection)

The TDA7801 is a new BCD technology quad

bridge amplifier for car audio applications.

■ Two I C bus addresses and 8-ch TDM mode

(only in PowerSO package)

Thanks to the BCD6 technology it is possible to

integrate a high performance D/A converter

together with powerful MOSFET outputs.

■ Optional non I C bus mode

■ Offset detector (play or mute mode)

■ Clipping detector (selectable level and

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.

■ CMOS compatible enable pin (3.3/5 V)

■ Full fault protection

This device is equipped with a full diagnostics

array that communicates the status of each

speaker through the I C bus. The possibility to

■ Four independent short circuit protections

■ Thermal protection (four levels)

■ ESD protection

control the configuration and behavior of the

device by means of the I C bus makes TDA7801

a very flexible machine.
