Using the multiplexer, multiple RTD types can be measured with a universal interface connected to the ADC. The ADC configuration must be changed for each type, setting different analog inputs and while using a single IDAC output. With changes to the configuration registers, two-, three-, and four-wire RTDs can all be measured with a four connection interface.
