The device can be used also as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability. The device is particularly designed to make the output stage of a stereo All-Digital High Efficiency (DDX™) amplifier capable to deliver an output power of 20W x 4 channels @ THD = 10% at Vcc 26V on 4Ω load in single ended configuration. It can also deliver 40 + 40W @ THD = 10% at Vcc 26V as output power on 8Ω load in BTL configuration and 60W @ THD = 10% at Vcc 32V on 8Ω in single paralleled BTL configuration. The input pins have threshold proportional to VL pin voltage. Figure 2.
