1.3.2.4.1.3.4.3 Attaching a voltage divider
A voltage divider is needed when the Analog In needs to be calibrated. This is required for adjusting the
measuring range when using a temperature sensor.
The image below depicts how to connect an RTD sensor resistance using the single-ended analog input.
The internal resistance R of the single-ended analog input is 20.4 kΩ and it is connected in parallel to the RTD
sensor.
