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.
