TDA1557Q 2 x 22w car radio power amplifier

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.
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.
