TDA7564B

4× 50W多功能四功率放大器，内置的诊断功能 4 x 50W multifunction quad power amplifier with built-in diagnostics features

Description

The is a new BCD technology QUAD BRIDGE type of car radio amplifier in 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.
