True digital audio amplifier (TDAA) is a new paradigm in digital audio. The TDAA system currently consists of the TAS5000 PCM-PWM modulator device + TAS5100A 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 TAS5100A 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 TAS5100A 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.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
