STA50813TR 40 V, 4.5 A quad power half-bridge digital audio amplifier
STA508 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 80 + 80 W @ THD = 10 % at VCC = 35 V output power on 8 Ω load.
In single BTL configuration is also capable to deliver a peak of 160 W @ THD = 10 % at VCC = 35 V on 4 Ω load. The input pins have threshold proportional to VL pin voltage.
