... Coarse and fine second order calibration of the sensitivity and offset. The MLX90326 can be calibrated to achieve 4V output span for a sensor output span in the 1.8mV/V to 63mV/V and can compensate 0.4mV/V to 97.2mV/V input offset depending on the sensor output span and on the desired MLX90326 output offset voltage ...

... The external temperature sensor is only needed for applications where the temperature surrounding the customer sensor is different from the temperature surrounding the MLX90326. In the ratio-metric application mode, to keep the accuracy, the same supply should be used for the customer sensor, the MLX90326 and an ADC that makes the digital conversion of the analog output signal. ...

... INM INP With the use of an external voltage regulator to supply the sensor, the MLX90326 as well as an ADC used for converting the analog output signal, the MLX90326 can be used in a non ratio-metric mode. An example of standard voltage regulator is the LM7805. C1, C2, R1 and R2 are the same as in the ratio-metric application mode ...
