STA518 Datasheet PDF - ST Microelectronics

The STA518 is a monolithic quad half-bridge Digital Audio Amplifier in multi-power 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 24W x 4 channels at 10% THD at VCC 30V into 4W load in single-ended configuration. The input pins have a threshold proportional to the VL pin voltage.
