FEATURES Low dissipation due to switching from Single-Ended  (SE) to Bridge-Tied Load (BTL) mode Differential inputs with high Common Mode Rejection  Ratio (CMRR) Mute/standby/operating (mode select pin) Zero crossing mute circuit Load dump protection circuit Short-circuit safe to ground, to supply voltage and  across load Loudspeaker protection circuit Device switches to SE operation at excessive junction  temperatures Thermal protection at high junction temperature (170°C) Diagnostic information (clip detection and  protection/temperature) Clipping information can be selected between THD = 2.5% or 10% GENERAL DESCRIPTION The TDA1563Q is a monolithic power amplifier in a  17-lead DIL-bent-SIL plastic power package. It contains  two identical 25 W amplifiers. The dissipation is minimized  by switching from SE to BTL mode when a higher output  voltage swing is needed. The device is primarily  developed ...
