2 DESCRIPTION
STA506A is a monolithic quad half bridge stage in
Multipower BCD Technology.
The device can be used as dual bridge or reconfig-
ured, 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 60 + 60W @
THD = 10% at V_cc 32V output power on 8Ω load and
80W @ THD = 10% at V_CC 36V on 8Ω load in single
BTL configuration. In single BTL configuration is also
capable to deliver a peak of 120W @THD = 10% at
V_CC = 32V on 4Ω load. The input pins have threshold
proportional to V_L pin voltage.
