The TDA7569LV is equipped with the most
complete diagnostics array that communicates
the status of each speaker through the I2C bus.
The dissipated output power under average
listening condition is significantly reduced when
compared to the conventional class AB solutions,
thanks to the patented solution. Moreover it has
been designed to be very robust against several
kinds of misconnections.
It is moreover compliant to the most recent OEM
specifications for low voltage operation (so called
'start-stop' battery profile during engine stop and
re-start), helping car manufacturers to reduce the
overall emissions and thus contributing to
environment protection.
