70 W power amplifier circuit

FEATURES: Very high output power, operating from a single low  supply voltage Low power dissipation, when used for music signals Switches to low output power at too high case  temperatures Few external components Fixed gain Differential inputs with high common mode rejection Mode select pin (on, mute and standby) Status I/O pin (class-H, class-B and fast mute) All switching levels with hysteresis Diagnostic pin with information about: Dynamic Distortion Detector (DDD) Any short-circuit at outputs Open load detector Temperature protection. No switch-on or switch-off plops Fast mute on supply voltage drops Quick start option (e.g. car-telephony/navigation) Low (delta) offset voltage at the outputs Load dump protection Short-circuit safe to ground, supply voltage and across  the load Low power dissipation in any short-circuit condition Protected against electrostatic discharge Thermally protected Flexible leads.
