DESCRIPTION
STA508 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
pin to Vdd pin, as single bridge with double current
capability, and as half bridge (Binary mode) with half
current capability.

The device is particularly designed to make the out-
put stage of a stereo All-Digital High Efficiency
(DDX™) amplifier capable to deliver 80 + 80W @
THD = 10% at V
cc
35V output power on 8Ω load.
In single BTL configuration is also capable to deliver
a peak of 160W @THD = 10% at V
CC
= 35V on 4Ω
load. The input pins have threshold proportional to V
