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 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). QUICK REFERENCE DATA Test conditions: VP = 14.4 V; RL = 4 ; Rs = 0 ; f = 1 kHz; Tamb = 25 °C; unless otherwise specified.
