2 DESCRIPTION
STA501A is a monolithic dual half bridge stage in
Multipower 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 V
cc
30V output power on 8
Ω
load. The input
pins have threshold proportional to V
L
pin voltage.
