DESCRIPTION
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.

20W BRIDGE AMPLIFIER FOR CAR RADIO
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, the TDA7240A protects the loudspeaker when
one output is short-circuited to ground.
