LMT01: RF susceptibility?

Hello John,

there are no known issues regarding RF immunity with this device. 

Which test standard are you testing to, and what output are you observing? Are you able to share the test results and setup parameters, as well as schematics and layout with our team to review? You can send me details in a private message if you wish. 

EMC test was a stepped freq. sweep from 80 to 1000 MHz.  We were shooting it with approx. 320 MHz at 10V/meter for susceptibility testing.  Orientation (Horiz/Vert, front, back, side A, side B) didn't really matter.  The temperature reading was effected by a negative coefficient.  e.g.  Ambient temp was 84 DegF, as freq. swept from 200 to 320 MHz, the reported temperature dropped from 84 to -10 DegF respectively.  

The readings from an ADS131 analog front end on our PCB were also effected in the 320 MHz +/- 25Mhz range.  This is mentioned because the AFE's temperature reading is used to scale the LMT01's temperature.  I don't know whether the issue resides with either of the TI parts, our power supply, both, etc.

I'm checking on the schematic/layout review.

Cannot easily rerun test.  It was run at an EMC/EMI facility.
