STA518 quad power half-bridge digital audio amplifier
STA518 is a monolithic quad half bridge stage in Multipower BCD Technology. The device can be used also as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability.
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.
