Hello Nikola,
Currently we do not have EMI data or layout recommendation for EMI immunity. TI does offer ISOTMP35, which is designed for measure temperature in high voltage environments. Please refer to the attached document PCB Design Guidelines For Reduced…
Hi Pravin,
In general, we recommend mounting the temperature sensing element as close as possible to the heat source to provide the closest and most accurate temperature as well as using cutouts to reduce thermal mass for improved response. In terms of…
ISOTMP35 may be of interest for a bus bar. LMT84 may be appropriate in TO-92. If a PCB can be mounted on or near the bus bar, then any temp sensor in our portfolio would be acceptable. ti.com/temperature

Hi Daniel,
Just so I understand, you are trying to sense temperature of a copper region across a HV isolation barrier? I would recommend looking at our new ISOTMP35 , which an analog temp sensor designed to be placed across an isolation barrier to directly…
Hi Michael,
What Meredith meant was that the thermal pad should be connected to SGND along with the other grounded pins on the TMP1075, but not extending the thermal pad copper to reach PGND which could introduce the noise transients you are worried about…
Hi Ala,
Thank you for sharing these details. Since your main concerns are maximizing accuracy while using an integrated ADC I would recommend looking at TMP236-Q1 . This analog temperature sensor offers a max temp accuracy of ±2.5 °C accross the full range…
