25 W high efficiency car radio power
amplifier
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.
