× 25 W BTL quad car radio power

amplifier

TDA8569Q

FEATURES

• Capable of driving 2 Ω loads

• Requires very few external components

• High output power

• Low output offset voltage

• Fixed gain

• Diagnostic facility (distortion, short-circuit and

temperature pre-warning)

• Good ripple rejection

• Mode select switch (operating, mute and standby)

• Load dump protection

load

• 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

• Pin compatible with the TDA8567Q.

GENERAL DESCRIPTION

The TDA8569Q is an integrated class-B output amplifier in

a 23-lead Single-In-Line (SIL) plastic power package.

It contains four amplifiers in BTL configuration, each with a

gain of 26 dB. The output power is 4

× 25 W in a 4 Ω load.

APPLICATIONS

• The device is primarily developed for car radio

applications.
