Product specification

TDA8565Q

FEATURES

• Requires very few external components

• High output power

• Fixed gain

• Diagnostic facility (distortion, short-circuit and

temperature detection)

• Good ripple rejection

• Mode select switch (operating, mute and standby)

• Load dump protection

• AC and DC short-circuit safe to ground and to VP

• 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

• Identical inputs.

GENERAL DESCRIPTION

The TDA8565Q is an integrated class-B output amplifier in

a 17-lead DIL-bent-to-SIL power package. It contains

4 × 12 W single-ended amplifiers.

APPLICATIONS

• The device is primarily developed for car radio

applications.
