YD1519B Datasheet | Wuxi Youda electronics

DESCRIPTION The YD1519B is an integrated class-B dual output amplifier in a 9-lead single in-line (SIL) plastic medium power package. The device is primarily developed for car radio applications. FEATURES - Requires very few external ponents for Bridge Tied Load (BTL),Stereo or BTL application; - High output power, Fixed gain, Good ripple rejection; - Identical inputs (inverting and non-inverting),Low offset voltage at output (important for BTL); - Mute/stand-by switch, No switch-on/switch-off plop; - Load dump protection, AC and DC short-circuit-safe to ground and Vcc, Thermally protected; - Reverse polarity safe; - Capability to handle high energy on outputs (Vcc=0V); - Protected against electrostatic discharge.
