Part Number: TAS2563

The following schematic is the typical application of the TAS2563 Smart Amp device along with some component value selection to consider when planning the schematic of a Smart Amp product in an audio design. It is recommended to follow the suggested component values and selection tips to optimize audio device performance. Please pay extra attentions to the highlighted cells in the table as they serve critical roles for the internal boost feature

Typical Application Schematic 

Component values selection suggestions and recommendations:

  1. Choose boost inductor and capacitor value indicated in the following table.
  2. Choose component derating that is greater or equal to the table specifications
  3. Choose the ratings of decoupling capacitors for VBST and PVDD to be greater than maximum output voltage
  4. Adjust the boost inductor range and boost capacitance in PPC3>TAS2563 EVM>Device Control>Channel Gain as shown in the following figure.
