THEORY OF OPERATION CIRCUIT INFORMATION The AD7414/AD7415 are standalone digital temperature sensors. The on-chip temperature sensor allows an accurate measurement of the ambient device temperature to be made. The 10-bit analog-to-digital converter converts the temperature measured into a twos complement ...
