Description

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 output stage of a stereo All-Digital High Efficiency (DDX™) amplifier capable to deliver 50 + 50W @ THD = 10% at Vcc 30V output power on 8W load and 80W @ THD = 10% at Vcc 36V on 8W load in single BTL configuration.

The STA505 input pins have threshold proportional to Ibias pin voltage.
