OPERATION—MEASURING TEMPERATURE The DS75LX measures temperature using a bandgap temperature-sensing architecture. An on-board delta-sigma analog-to-digital converter (ADC) converts the measured temperature to a digital value that is calibrated in degrees celsius; for Fahrenheit applications a lookup table or conversion routine ...
