The sensor should meet these characteristics:
If the sensor maximum output is less than 0.45 V, using the internal PGA helps improve the resolution of the measurements. For example if the maximum output voltage of the sensor is 0.35 V, using a PGA gain of 2 improves the resolution of the ADC result.
Also, this device includes hardware support for thermistors. The device can support up to two thermistors on TEMP1 and TEMP2.
The ADC (sigma-delta 14-bit) on this device is a slow acquisition one. Up to 1 second is required for a conversion to complete with full accuracy. Shorter conversion times are possible if 14-bit accuracy is not needed.
