STA518 quad power half-bridge digital audio amplifier
The device is particularly designed to make the output stage of a stereo All-Digital High Efficiency (DDX™) amplifier capable to deliver an output power of 24W x 4 channels @ THD = 10% at Vcc 30V on 4W load in single ended configuration. It can also deliver 50 + 50W @ THD = 10% at Vcc 29V as output power on 8W load in BTL configuration and 70W @ THD = 10% at Vcc 34V on 8W in single paralleled BTL configuration.
