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 Vddpin, 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 VCC30 V into a 4 Ω load in single-ended configuration.

It can also deliver 50 + 50 W @ THD = 10% at VCC29 V as output power into an 8 Ω load in BTL configuration and 70 W @ THD = 10% at VCC34 V into 8 Ω in a single paralleled BTL configuration.

The input pins have a threshold proportional to the VLpin voltage.
