The STA510F 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, and as half-bridge (binary mode). The device is particularly designed to make the output stage of a stereo all-digital high-efficiency (FFX) amplifier capable of delivering 100 W + 100 W output power into 6 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 device is fully compatible with the FFX®driver device. The input pins have a threshold proportional to VLpin voltage.
