Description

The TDA7569BDLVPD is the most advanced

BCD technology quad bridge car radio amplifier,

including a wide range of innovative features.

The TDA7569BDLVPD is equipped with the most

complete diagnostics array that communicates

the status of each speaker through the I2C bus.

The differential input stage improves the

disturbance rejection.

The dissipated output power under average

listening condition is significantly reduced when

compared to the conventional class AB solutions,

thanks to the innovative internal design. 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),

helping car manufacturers to reduce the overall

emissions and thus contributing to environment

protection.
