2 x 25 W audio amplifier circuit TDA1563Q
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 for car radio applications.
