Adding a Audio Freq filter to the output of TPA2011D1 device

Other Parts Discussed in Thread: TPA2011D1

I am looking for any recommendation that Ti may have to pass audio frequencies at the output of TPA2011D1 device

Thanks

  • Hi Debabrata,

    This is a filter-free device so it could be used without output filter. You can take a look at "When to use an output filter" section on TPA2011D1 D/S for more details about filter-free and ferrite bead filter options.
    Although if you want to see the output signal waveform in an oscilloscope you can use the recommended output RC filter used in the TPA2011D1 EVM. This filter was used to obtain the graphs of the D/S. Details about this filter are in "Test setup for graphs" section.
