Features
! ! ! ! ! ! !
Minimum input output pulse width distortion 150 mW Rdson complementary DMOS output stage CMOS compatible logic inputs Thermal protection thermal warning output Under-voltage protection No power-on, power- off sequence required 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. The input pins have a threshold proportional to VL pin voltage. PowerSO36 with exposed pad (or slug) up
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.
