8.2 Ratio-metric mode with no external temperature sensor.
C1, C2, C3, C4 and R2 have the same values as for the ratio-metric application with use of external
temperature sensor.
The internal temperature sensor can be used when the temperature surrounding the customer sensor and
the MLX90326 is the same.
8.3 Non Ratio-metric mode with external temperature sensor.
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. C4 has a typical value of 330nF and C3 of 100nF in this application mode.
