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.
