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).

FEATURES

? Very high output power, operating from a single low supply voltage

? Low power dissipation, when used for music signals

? Switches to low output power at too high case temperatures

? Few external components

? Fixed gain

? Differential inputs with high common mode rejection

? Mode select pin (on, mute and standby)

? Status I/O pin (class-H, class-B and fast mute)

? All switching levels with hysteresis

? Diagnostic pin with information about:

– Dynamic Distortion Detector (DDD)

– Any short-circuit at outputs

– Open load detector

– Temperature protection.

? No switch-on or switch-off plops

? Fast mute on supply voltage drops

? Quick start option (e.g. car-telephony/navigation)

? Low (delta) offset voltage at the outputs

? Load dump protection

? Short-circuit safe to ground, supply voltage and across the load

? Low power dissipation in any short-circuit condition

? Protected against electrostatic discharge

? Thermally protected

? Flexible leads.
