DESCRIPTION
The true digital audio amplifier (TDAA) is a new
paradigm in digital audio. One TDAA system consists of
the TAS5015 PCM-PWM modulator device plus a
discrete back-end TDAA power output. This system
accepts a serial PCM digital audio stream and converts
it to a 3.3-V PWM audio stream (TAS5015). The
discrete back-end TDAA 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 TAS5015 is an innovative,
cost-effective, high-performance 24-bit stereo
PCM-PWM modulator based on Equibit technology.
The TAS5015 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 (Fs) of 44.1 kHz, 48 kHz, 88.2 kHz, 96
kHz, 176.4 kHz, and 192 kHz. The TAS5015 also
provides a de-emphasis function for 44.1-kHz and
48-kHz sampling rates.
