TDA1562Q
Information as of 2000-08-22
TDA1562Q; 70 W high efficiency power amplifier with diagnostic facility
The TDA1562Q 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, radio and boosters) as well as mains fed applications (e.g. midi/mini audio
combinations and TV sound).
