DESCRIPTION  
D
TAS5015 Plus Discrete Back-End TDAA  
System — High-Quality Digital Audio  
Amplification  
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,

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.
