As an extension to the voltage ratings given in the Absolute Maximum Ratings section of the TAS5111, TAS5112, TAS5121, and TAS5122 data sheets, this application note gives a more explicit description of the maximum limit for peak voltage vs. time on the BST and OUT pins. Additionally, a measurement technique and test setup is described and application design guidelines given on how to avoid exceed - Power Supply Recommendations for DVD ReceiversPDF, 153 Kb, File published: May 4, 2005
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 - PSRR for Purepath Digital Audio AmplifiersPDF, 159 Kb, File published: Apr 15, 2005
