Product specification

2 x 22 W BTL stereo car radio power

amplifier

TDA1552Q

GENERAL DESCRIPTION

The TDA1552Q is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package.

The circuit contains 2 x 22 W amplifiers in Bridge Tied Load (BTL) configuration. The device is primarily developed for

car radio applications.

Features

• Mute/stand-by switch

• Load dump protection

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

P

• Thermally protected

• Reverse polarity safe

• Capability to handle high energy on outputs (V

• Protected against electrostatic discharge

• No switch-on/switch-off plop

• Low thermal resistance

• Flexible leads.
