I found the ADAU1761 with internal AD-/DA-U´s. My questions, is there a reconstructionfilter in the DAU´s to restore the continious time signal?
The ADAU1761 includes oversampled digital filters for both ADCs and DACs, so no external antialias and reconstruction filters are needed. Find the specs for these filters in the data sheet:
Thank you for your respone.
I thought digital interpolationfilter are used to lower the design expenses.
lower the design expenses for the analog filter
