2 / 10 page May 1992 2 Philips Semiconductors Product specification 2 x 22 W BTL stereo car radio power amplifier with speaker protection TDA1557Q FEATURES • Requires very few external components • High output power • Low offset voltage at output • 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) • Protected against electrostatic discharge • No switch-on/switch-off plop • Flexible leads • Low thermal resistance. GENERAL DESCRIPTION The TDA1557Q is a monolithic integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package. The device contains 2 × 22 W amplifiers in BTL configuration and has been primarily developed for car radio applications. QUICK REFERENCE DATA ORDERING INFORMATION Note 1. SOT141-6; 1996 August 23.
