One TDAA system consists of the TAS5001 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 (TAS5001). 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, highefficiency digital audio applicable to many audio systems developed for the digital age. The TAS5001 is an innovative, cost-effective, high-performan...
