GENERAL DESCRIPTION The TDA1562 is a monolithic integrated 70 W/4 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).
