Philips Semiconductors Product specification
2×25 W high efficiency car radio poweramplifier 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
•Thermalprotection 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
twoidentical 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.
