Hello Joseph, Thanks for your great support, there are some feedback about your questions below, please also give your comments. Now they want to use TGMAA103G39HAD(purple curve), the resistor range is about from 20K to 500 ohm, what's the reference resistor they need to choose? 2. For the series resistance coming out of the TS3A5017 , now they use 0 ohm resistor, it can be adjusted according to the application. 3. Becuase this circuit is for PT100 design before, it is 3 wires, now they want to detect NTC which is 2 wires, so they need to change 3 wires to 2 wires, you can check the picture below, they short a- and A- pins, so aA+ and a- pins are 2 wires and connect to NTC. 4. According to NTC spec, do you have any suggest solution?, i think our ADS1248 is not a good choice to detect NTC. 5. For TS3A5017 , they use it to switch 4 channles RTD, do you have reference circuit of our ADS1248 to detect 4 channels PT100? and for PSM712, do we have new solution to replace it? 6. Can you also share the power noise spec of our ADS1248 ? thanks Regards, Nanfang
