ADS122U04EVM: Error in EVM BOM

Part Number: ADS122U04EVM
Other Parts Discussed in Thread: ADS122U04

There's an error in the BOM for the ADS122U04 EVM board in the May 2017 user's guide on page 32... If you look below the 0.01uF and 0.1uF capacitors have the exact same TDK part number despite completely different specs. I couldn't find TDK capacitor with those specs so I have no idea what the correct part number should be. 

  • Kudos Doug!

    You found a cut-paste error.  For the 0.1uF cap the AVX part number should be 0603YC104JAT2A.  Keep in mind that the actual passive components installed on the EVM may not be what is listed in the BOM.  The parts may have a substitute installed due to availability of the component listed in the BOM.  The key factor is the substitute component must follow the characteristics in the BOM description as to value, voltage and grade (or better grade).  There is usually nothing special regarding the components used, but rather common components used in our TI libraries.

    Best regards,

  • Hi Bob,

    I figured it was a copy / paste error, I just happened to see it when I was boiling down the EVM design to a small breakout board.
