The TDA7240A is a 20W bridge audio amplifier IC

designed specially for car radio applications.

Thanks to the low external part count and compact

Heptawatt 7-pin power package the TDA7240A

occupies little space on the printed circuit board.

Reliable operation is guaranteed by a comprehen-

sive array of on-chip protection features. These in-

clude protection against AC and DC output short

circuits (to ground and across the load), load dump

transients, and junction overtemperature. Additio-

nally, theTDA7240Aprotectstheloudspeakerwhen

one output is short-circuited to ground.
