The STA510A is a monolithic, quad, half-bridge stage in multipower BCD technology. The device can be used as dual-bridge or reconfigured, by connecting the CONFIG pin to the VDD pin, as single-bridge with double current capability, or as half-bridge (binary mode) with half current capability.

The device is particularly designed to make the output stage of a stereo all-digital high-efficiency (DDX) amplifier, which employs a pulse-width modulator driver. The STA510A is capable of delivering an output power of 50 W into 3 Ω loads with THD = 10% and VCC = 36 V. In single BTL configuration the device can deliver 200 W into a 3 Ω load with THD = 10% and VCC = 36 V.

The input pins have a threshold proportional to VL pin voltage.
