DESCRIPTIONSTA505 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 50 + 50W @
THD = 10% at Vcc 30V output power on 8Ω load and
80W @ THD = 10% at Vcc 36V on 8Ω load in single
BTL configuration. The input pins have threshold pro-
portional to VL pin voltage.

Table 3. Functional Pin Status(*) : The pin is open collector. To have the high logic value, it needs to be pulled up by a resistor.
(**): To put CONFIG = 1 means connect Pin 24 (CONFIG) to Pins 21, 22 (Vdd)
