UDESCRIPTION
t4STA500 is a monolithic quad half bridge stage in Mul-
tipower BCD Technology. The device can be used as
dual bridge or reconfigured, by connecting CONFIG
epin to Vdd pin, as single bridge with double current
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.
