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.

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 V_cc = 39 V. In single BTL
configuration the device can deliver 200 W into a
4-Ω load with THD = 10% and V_cc = 39 V.
The device is fully compatible with the DDX^®
driver device.
The input pins have a threshold proportional to V_L
pin voltage.
