GENERAL DESCRIPTION The TDA1555Q 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 Distortion detector Circuit Diagram: TDA1555Q 4 x 11 W single-ended  TDA1555Q 2 x 22 W power amplifier with distortion detector
