DESCRIPTIONSTA501 is a monolithic dual half bridge stage in Mul-
tipower BCD Technology.
The device is particularly designed to make the out-
put stage of a mono All-Digital High Efficiency
(DDX™) amplifier capable to deliver 50W @ THD =
10% at Vcc 30V output power on 8Ω load. The input
pins have threshold proportional to Ibias pin voltage.
