Q: What is the aproximate power consumption of MAX31911 while powered from a 12V source and how much lower it is while using a 5V supply conected to the 5VOUT pin?
A: Using a 12V supply, the MAX31911EVKIT drew 1.446mA of current. Bypassing the regulator by connecting 5V to the 5VOUT pin resulted in 1.416mA of current draw, saving about 10.3mW. This test was performed on the MAX31911EVKIT using the onboard RREF (15 kOhm) and disabling the LED from pulling current during the fault condition (5V at the 5VOUT pin) by removing R11.
