Hi Paulo,
That configuration looks to be ok, but you may find that different component values may be desired for best ratiometric matching. Also, if you are to use 3.3V for the analog supply, you must make sure your design will provide enough margin for IDAC voltage compliance. If you use 1mA for IDAC current, you will not have enough margin throughout your measurement range. Please re-read my first response regarding IDAC compliance voltage.
When using a thermistor, the approach is similar. A 10k resistance response will cause some error as you will be outside the IDAC compliance if you use the same settings as you do for the RTD, but you should read a full-scale response for any voltage created larger than the reference. Normal operating conditions should be fine.
Best regards,
