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 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)

• 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
