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, high-performance 24-bit stereo PCM-PWM modulator based on Equibit technology. The TAS5015 has a wide variety of serial input options including right-justified (16, 20, or 24 bits), IIS (16, 20, or 24 bits), left-justified (16 bits), or DSP (16 bits) data formats. It is fully compatible with AES standard sampling rates (Fs) of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. The TAS5015 also provides a de-emphasis function for 44.1-kHz and 48-kHz sampling rates.
