Description 

The 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 the CONFIG pin to the Vdd pin, as a single bridge with double current capacity. The device is particularly designed to make the output stage of a stereo all-digital high-efficiency (DDX™) amplifier capable of delivering an output power of 24 W x 4 channels @ THD = 10% at VCC 30 V into a 4  load in single-ended configuration. It can also deliver 50 + 50 W @ THD = 10% at VCC 29 V as output power into an 8 load in BTL configuration and 70 W @ THD = 10% at VCC 34 V into 8 in a single paralleled BTL configuration. The input pins have a threshold proportional to the VL pin voltage.
