MAX31856 is precise 19bit Thermocouple to Digital Converter with Linearization and have on T+ T- input protection on +-45V. The range can be increased by resistors, but it brings a number of problems.
I need to increase resistance to ESD.
My idea is add on T+ T- ESD protection diodes any as PESD5V0S2UQ
My question
1. It's a good idea or the ESD diode affects the measurement of the thermocouple
2. If not, I can say that the thermocouple is junk
IEC 61000-4-2; level 4 (ESD) > 15 kV (air); > 8 kV (contact)
MIL-STD-883; class 3 (human body model) > 4 kV

one more question.
I do not see the specification for DRDY in the datasheet.
I can dirrenct connect 4 this output on one MCU input?
