MLX90326
Analog 0-5V Sensor Interface IC
standard voltage regulator is the LM7805. C1, C2, R1 and R2 are the same as in the ratio-metric application
mode. C4 has a typical value of 330nF and C3 of 100nF in this application mode.
8.4 Non Ratio-metric mode with no external temperature sensor.

In this application mode the LM7805 generates the supply for the sensor, for the MLX90326 and for an ADC
used to convert the analog output signal in a digital value. C1, C2, C3, C4 and R2 are the same as in the non
ratio-metric application mode with external temperature sensor.
