2

× 40 W/2 Ω stereo BTL car radio power

amplifier with diagnostic facility

TDA8563Q

FEATURES

• Requires very few external components

• High output power

• 4 Ω and 2 Ω load impedance

• Low output offset voltage

• Fixed gain

• Diagnostic facility (distortion, short-circuit and

temperature detection)

• Good ripple rejection

• Mode select switch (operating, mute and standby)

• Load dump protection

• Low power dissipation in any short-circuit condition

• Thermally protected

• Reverse polarity safe

• Electrostatic discharge protection

• No switch-on/switch-off plop

• Flexible leads

• Low thermal resistance.

GENERAL DESCRIPTION

The TDA8563Q is an integrated class-B output amplifier in

a 13-lead single-in-line (SIL) power package.

It contains 2

× 40 W/2 Ω amplifiers in BTL configuration.

The device is primarily developed for car radio

applications.
