Introduction
The true digital audio amplifiers (TDAA) system consists of a PCM-PWM
modulator device and a PWM power output device. The PCM-PWM processor
accepts a serial PCM digital audio stream and converts it to a 3.3-V PWM
audio stream. The TDAA output stage provides a large-signal PWM output.
The digital PWM signal is then demodulated, providing power output for
driving loudspeakers. This patented technology provides low cost, high
quality, highly efficient digital audio applicable to many audio systems
developed for the digital age.
The TAS5026REF reference design demonstrates the integrated circuit
TAS5026 from Texas Instruments (TI). The TAS5026 is a 24-bit multichannel
digital pulse width modulator based on Equibit

technology. The TAS5026 is
designed to drive up to six digital power devices to provide six channels of
digital audio amplification. The digital power devices can be conventional
monolithic power stages (such as the TAS5110 or the TAS5112) or discrete
differential power stages using gate drivers and MOSFETs.
