internal temperature sensor of ADuCM3029

Question asked by fiachra-harrington on May 16, 2018

hello,

im programming the ADuCm3029 in IAR to take the temperature reading from the internal temperature sensor , there are functions to do this in the file adi_adc_v1.c that is provided in some of the examples. after powering up, enabling and calibrating the sensor i have it reading out 3000 times to get values. But instead of being at about 25C its reading around 400 at this temperatures, also this reading changes significantly with changing value of the Vbat, which is important as my application will be run off 3V batteries. Any suggestions?
