Description

The TDA7564B is a new BCD technology QUAD

BRIDGE type of car radio amplifier in

Flexiwatt25

PowerSO36

Flexiwatt25/PowerSO36 package specially

intended for car radio applications.

Thanks to the DMOS output stage the TDA7564B

has a very low distortion allowing a clear powerful

sound. Among the features, its superior efficiency

performance coming from the internal exclusive

structure, makes it the most suitable device to

simplify the thermal management in high power

sets.

The dissipated output power under average

listening condition is in fact reduced up to 50%

when compared to the level provided by

conventional class AB solutions. This device is

equipped with a full diagnostics array that

communicates the status of each speaker through

the I2C bus.
