2 / 11 page May 1992 2 Philips Semiconductors Product specification 4 x 11 W single-ended or 2 x 22 W power amplifier TDA1554Q 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 V P • Thermally protected • Reverse polarity safe • Capability to handle high energy on outputs (V P = 0 V) • Protected against electrostatic discharge • No switch-on/switch-off plop • Low thermal resistance • Identical inputs (inverting and non-inverting) • Flexible leads.
