resistive temperature device (RTD), or other temperature sensors. But, if I
understand the manual of the evaluation board, the EVAL-ADN8831 can only be
used in combination of a thermistor. Can I modify the board so that it can be
used with a resistive temperature device (RTD), for example PT100.
Yes, you can modify the EVB to adopt the positive temperature coefficient
sensor, such as RTD. You may modify the EVB design in the way shown on the
The challenges are: the RTD thermal response time constant, and sensed
temperature vs. resistance, and the chop 1 amplifier gain control. You need to
do your own homework with the RTD design.
