The true digital audio amplifier (TDAA) is a new paradigm in digital audio. One TDAA system consists of the TAS5015 PCM-PWM modulator device plus a discrete back-end TDAA power output. This system accepts a serial PCM digital audio stream and converts it to a 3.3-V PWM audio stream (TAS5015). The discrete back-end TDAA then provides a large-signal PWM output. This digital PWM signal is then demodulated, providing power output for driving loudspeakers. This patented technology provides low-cost, high-quality, high-efficiency digital audio applicable to many audio systems developed for the digital age. The TAS5015 is an innovative, cost-effective,
