GENERAL DESCRIPTION

The TDA1554Q is an integrated class-B output amplifier in a 17-lead single-in-line (SIL) plastic power package. The circuit contains 4 x 11 W single-ended or 2 x 22 W bridge amplifiers. The device is primarily developed for car radio applications.

Features

• Requires very few external components

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

• High output power

• Low offset voltage at outputs (important for BTL)

• Fixed gain

• Good ripple rejection

• Mute/stand-by switch

• Load dump protection

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

• Thermally protected

• Reverse polarity safe

• Capability to handle high energy on outputs (VP = 0 V)

• Protected against electrostatic discharge

• No switch-on/switch-off plop

• Low thermal resistance

• Identical inputs (inverting and non-inverting)

• Flexible leads.
