TMP117: Datasheet revision inquiry.

Part Number: TMP117

Hello.

I have used the TMP117AIDRVR in the past and trying to use this part again for another project recently.

However, there is a difference between the datasheet in 2019 and the datasheet revised in 2022, so I want to know why.

In the 2019 datasheet, the Noise-Reduction Techniques part marked in blue is missing.

Please find the checked point.

  • Dear Shin - 

    The RC combination form a low pass filter. In the figure that was removed, the values make it very specific to ~3.184kHz cutoff frequency, and therefore perhaps not useful to all directly, and might even be mis-leading to the uninformed, because it is not unique or specific to the TMP117, it is just a technique that could be employed in the (or any) circuit. The technique is still valid, if you want to leverage on this or any other IC or system, or find and eliminate/shield any noise sources in your system at the source, instead of filtering, that is a overall system design choice.
