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, high efficient digital audio applicable to many audio systems
developed for the digital age.
The TAS5110D6REF reference design demonstrates the integrated circuit
TAS5110DAD from Texas Instruments (TI). The board does not contain any
PWM processors. A separate and compatible PWM processor board (such as
TAS5026REF) is available.
The TAS5110 is a single channel PWM power audio device. It contains
integrated gate drivers, four matched and electrically isolated
enhancement-mode N-channel power DMOS transistors, and protection and
fault-reporting circuitry. This device is optimized for use with the TAS50XX
PWM processor family.
Together with the TAS5026REF module or the TAS5036REF module, the
TAS5110D6REF module is a complete true digital audio amplifier system,
which includes digital volume control, headphone amplifier, and a subwoofer
output.
