the load
•
Low power dissipation in any short-circuit condition
•
Protected against electrostatic discharge
•
Thermally protected
•
Flexible leads.
GENERAL DESCRIPTION
The TDA1562 is a monolithic integrated 70 W/4
Ω
Bridge-Tied Load (BTL) class-H high efficiency power
amplifier in a 17 lead DIL-bent-SIL plastic power package.
The device can be used for car audio systems (e.g.
car radios and boosters) as well as mains fed applications
(e.g. midi/mini audio combinations and TV sound).
