Description
STA510F is a monolithic, quad, half-bridge stage in Multipower BCD technology. The device can be used as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability, and 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 (FFX) amplifier capable of delivering 100 W + 100 W output power into 8- loads with THD = 10% and Vcc = 39 V. In single BTL configuration the device can deliver 200 W into a 4- load with THD = 10% and Vcc = 39 V. The device is fully compatible with the DDX driver device.
