DESCRIPTION
True digital audio amplifier (TDAA) is a new paradigm
in digital audio. The TDAA system currently consists of
the TAS5000 PCM-PWM modulator device + 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 (TAS5000). 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-efficient digital audio applicable to many audio
systems developed for the digital age. The TAS5100 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. Also, included are protection and
fault-reporting circuitry. This device is optimized for use
with the TAS5000 digital modulator.
