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 or operating mode selectable by pin Load dump protection circuit Short-circuit safe to ground; to supply voltage and  across load Loudspeaker protection circuit Thermal protection at high junction temperature Device switches to single-ended operation at high  junction temperature Clip detection at 2.5 % THD Diagnostic signal indicating clipping, short-circuit  protection and pre-warning of thermal protection. GENERAL DESCRIPTION The TDA1565TH is a monolithic power amplifier in a  20-lead heatsink small outline plastic package. It contains  two identical 40 W amplifiers. Power dissipation is  minimized by switching from SE to BTL mode only when a  higher output voltage swing is needed. The device is  developed primarily for car rad...
