RTD readout

Hi, I am looking for 1mA current source for PT1000 so that I can read the voltage across the PT1000 proportional to the change in resistance. Any suggestion on that please ?

Hello johnpeter,

I hope all is great with you. Thank you for using the NXP communities.

Unfortunately, we do not offer any current source within our portfolio. Please accept my apologies.

In case it is useful for you, you may review to our Power Management portfolio as a reference.

Regards,

David

Thank you very much for your fast reply. I will have a look at PMICs for power management on the PCBs.

Meanwhile, can you please check and let me know if NXP offers power provider devices (linear regulators and DC-DC converters) that can work in the radiation environment with TID requirement of 30 krad or maybe even less 10 krad.
