A7240
LINEAR INTEGRATED CIRCUIT
20W BRIDGE AMPLIFIER FOR
CAR RADIO
DESCRIPTION
The UTC A7240 is a 20W bridge audio amplifier IC and designed
for car radio applications.
A comprehensive array of on-chip protection, include protection
against AC and DC output short circuits (to ground and across the
load), load dump transients, and junction over temperature, is
feature to provide reliable operation. Furthermore, the UTC A7240
protects the loudspeaker when one output is short-circuited to
ground.
FEATURES
* Few External Components
* Output Protected Against short Circuits to Ground and Across
Load
* Dump Transient
* Thermal Shutdown
* Loudspeaker Protection
* High Current Capability
* Low Distortion/Low Noise
