Preliminary specification

2

× 24 W BTL or 4 × 12 W single-ended

car radio power amplifier

TDA8564Q

FEATURES

• Requires very few external components

• High output power

• Flexibility in use - Quad single-ended or stereo BTL

• 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

• Identical inputs (inverting and non-inverting).

GENERAL DESCRIPTION

The TDA8564Q is an integrated class-B output amplifier in

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

4

× 12 W single-ended or 2 × 24 W bridge amplifiers.

APPLICATIONS

• The device is primarily developed for car radio

applications.
