AB  - A digital power amplifier topology is proposed optimized specifically for use with DSD-type data streams. The configuration enables direct interfacing of DSD data with no requirement for intermediate signal processing or analogue-to-digital conversion. The output architecture exploits a classic H-bridge configuration and uses a novel form of ac data coupling to simplify internal interface circuitry. Wide range gain control is enabled through modulation of the output-stage power supply voltage that also improves power efficiency at low gain settings. Consideration is given to finite pulse rise time and a modified DSD data format is investigated.
