The device is primarily developed for multimedia applications.TDA1517ATW 主要特性：? Requires very few external components? Flexibility in use: mono Bridge-Tied Load (BTL) and stereo Single-Ended (SE); it should be noted that in stereo applications the outputs of both amplifiers are in opposite phase? High output power? Low offset voltage at output (important for BTL)? Fixed gain? Good ripple rejection? Mode select switch (operating, mute and standby)? AC and DC short-circuit safe to ground and VP? Electrostatic discharge protection? Thermal protection? Reverse polarity safe? Capable of handling high energy on outputs (VP = 0 V)? No switch-on/switch-off plop? Low thermal resistance.
