Description

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) with half current

capability.

PowerSSO36 with

exposed pad (or slug) up

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-Ω loads with

THD = 10% and Vcc = 39 V. In single BTL

configuration the device can deliver 200 W into a

4-Ω load with THD = 10% and Vcc = 39 V.

The device is fully compatible with the DDX®

driver device.

The input pins have a threshold proportional to VL

pin voltage.
