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 radio applications.

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).
