Dear Sir,
I am using LMP90100 ADC for our prototype design of temperature profile controller, We are using RTD as temperature sensor. We are communicating with LMP90100. We are getting correct data from LMP90100. The problem we are facing is the ADC is stop responding after sometime, say half, one, two, or may sometime after four hour. I am not able to get data/communicate with LMP90100, once it is stop responding. The only solution is I need to power cycle the LMP90100. I tried resetting MCU; I also tried resetting SPI communication from MCU but not getting any response. I also tried by decreasing RTD excitation current from 1mA to 500uA to reduce internal heating but failed; I must need to power cycle to get response from LMP90100. Please let me know how I can prevent LMP90100 from getting hang.
