DESCRIPTION
The true digital audio amplifier (TDAA) is a new
paradigm in digital audio. One TDAA system consists of
the TAS5001 PCM-PWM modulator device + TAS5100
PWM power output device. This system accepts a serial
PCM digital audio stream and converts it to a 3.3-V
PWM audio stream (TAS5001). The TAS5100 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 TAS5001 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,
and 96 kHz. The TAS5001 also provides a de-emphasis
function for 44.1-kHz and 48-kHz sampling rates.
