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.
