This report describes the conversion of pulse-code-modulated (PCM) to pulse-width-modulated (PWM) signals using Texas Instruments TDAA modulation devices (TAS50xx) and signal amplification using Texas Instruments family of H-bridge output stages (TAS51xx). It includes a detailed discussion of power supply voltage requirements, output circuit filters, and thermal dissipation. An example stereo appl

Selecting the optimal power supply for a non feed back digital amplifier can bechallenging. Music is dynamic, so the power consumption is changing dramatically,from almost zero to maximum within a few ms.Designing the power supply so powerful that it can deliver the total amplifier outputpower continuously is too costly and usually unnecessary.Designing the power supply too small gives p
