TDA1562Q

INTEGRATED CIRCUITS DATA SHEET TDA1562Q 70 W high efficiency power amplifier with diagnostic facility Preliminary specification File under Integrated Circuits, IC01 1998 Apr 07 Philips Semiconductors Preliminary specification 70 W high efficiency power amplifier with diagnostic facility 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 GENERAL DESCRIPTION Fast mute on supply voltage drops TDA1562Q 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. The TDA1562Q 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. ...
