Power Supply Ripple Distortion
The TAS5710 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. A 32-bit
datapath eliminates the need for pre-scaling before processing and preserves signal integrity without sacrificing
dynamic range. A digital audio processor with fully programmable digital filters allows designers to custom tune
speakers for optimum sound in small enclosures. A programmable DRC can adjust power levels for a scaleable
design while also enabling night-mode listening modes.
The closed-loop architecture allows the device to operate from poorly regulated supplies. Figure 1 below shows
the benefit of the feedback architecture when a noisy supply (1kHz, 500mVpp ripple) modulates a 10kHz audio
input. The figure shows a 40dB improvement in sideband suppression when compared to an open-loop design.
This correlates directly to a 24dB improvement in distortion as seen in Figure 2.
