Description
STA516B 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 (DDX™) amplifier capable to deliver 160 + 160 W @ THD = 10 % at V load and 320 W @ THD = 10 % at V load in single BTL configuration.
