STMicroelectronics TDA7240A

The TDA7240A is a 20W bridge audio amplifier IC designed specially for car radio applications. These include protection against AC and DC output short circuits (to ground and across the load), load dump transients, and junction overtemperature. Thanks to the low external part count and compact Heptawatt 7-pin power package the TDA7240A occupies little space on the printed circuit board.
