† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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 tream 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.
