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 Requires very few external components High output power Low offset voltage at outputs 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 Flexible leads.
