True digital audio amplifier (TDAA) is a new paradigm in digital audio. 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 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz.
The TAS5012 also provides a de-emphasis function for 44.1-kHz and 48-kHz sampling rates.
