DESCRIPTION
The true digital audio amplifier (TDAA) is a new
paradigm in digital audio. One TDAA system consists of
the TAS5010 PCM-PWM modulator device + a
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 (TAS5010). 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 TAS5010 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 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz,
176.4 kHz, and 192 kHz. The TAS5010 also provides a
de-emphasis function for 44.1-kHz and 48-kHz
sampling rates.
