Product Summary

The STA505 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 STA505 is particularly designed to make the out-put stage of a stereo All-Digital High Efficiency (DDX) amplifier capable to deliver 50 + 50W @ THD = 10% at Vcc 30V output power on 8Ω load and 80W @ THD = 10% at Vcc 36V on 8Ω load in single BTL configuration. The input pins have threshold proportional to VL pin voltage.
