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.
