te P ct(s) DESCRIPTION
le u STA500 is a monolithic quad half bridge stage in Mul-
d tipower BCD Technology. The device can be used as
so ro dual bridge or reconfigured, by connecting CONFIG
b P pin to Vdd pin, as single bridge with double current
- O te capability, and as half bridge (Binary mode) with half
current capability.
The device is particulary designed to make the output
stage of a stereo All-Digital High Efficiency (DDX™)
amplifier capable to deliver 30 + 30W output power
on 8Ω load and 60W on 8Ω load in bridge BTL con-
figuration or mono 60W on 4Ω load. The input pins
have threshold proportional to Ibias pin voltage.
