Description
The TDA75612LV is a new quad bridge car radio
amplifier, designed in BCD technology, in order to
include a wide range of innovative features in a
very compact and flexible device.
The TDA75612LV is equipped with the most
complete diagnostics array that communicates
the status of each speaker through the I2C bus.
TDA75612LV has been designed to be very
robust against several kinds of misconnections.
The TDA75612LV is equipped with the SSR
(speaker safety routine), a procedure able to
check the offset at the speakers and automatically
shut down the power amplifier in case of
dangerous DC voltage.
It is moreover compliant to the most recent OEM
specifications for low voltage operation (so called
'start-stop' battery profile during engine stop),
helping car manufacturers to reduce the overall
emissions and thus contributing to environment
protection.
