One TDAA system consists of the TAS5012 PCM-PWM modulator device + TAS5110 PWM power output device. This system accepts a serial PCM digital audio stream and converts it to a 3.3-V PWM audio stream (TAS5012). The TAS5110 device 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 TAS5012 is an innovative, cost-effective, high-performance 24-bit stereo PCM-PWM modulator based on Equibit technology. It 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 of 32 k Hz, 44.1 k Hz, 48 k Hz, 88.2 k Hz, 96 k Hz, 176.4 k Hz, and 192 k Hz. The TAS5012 also provides a de-emphasis function for 44.1-k Hz and 48-k Hz sampling rates.
