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) Load dump protection circuit Short-circuit safe to ground, to supply voltage and  across load Loudspeaker protection circuit Offset detection for each channel Device switches to single-ended operation at excessive  junction temperatures Thermal protection at high junction temperature (170°C) Clip detection at THD = 2.5 % Diagnostic information  (clip/protection/prewarning/offset). GENERAL DESCRIPTION The TDA1564 is a monolithic power amplifier in a 17-lead  single-in-line (SIL) plastic power package. It contains two  identical 25 W amplifiers. The dissipation is minimized by  switching from SE to BTL mode, only when a higher output  voltage swing is needed. The device is primarily  developed for car radi...
