TDA7564 データシート - STMicroelectronics

DESCRIPTION
The TDA7564 is a new BCD technology QUAD BRIDGE type of car radio amplifier in Flexiwatt25 package specially intended for car radio applications. Thanks to the DMOS output stage the TDA7564 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.
