Hi, support team
My customer has the questions as follow:
When using ADS1247 external reference voltage, if I float REFOUT/REFCOM pin, I want to know the answers to the following questions：
1. What impact will it have on chip use and chip operate?
2. What impact will it have on the measured value?
3. Are there any other that need attention and knowledge？
(The internal reference and IDAC current source are not used, and the customer already knows that REFCOM recommends connecting GND and REFOUT recommends connecting capacitance.)
Thanks so much.
Best regards,
Yuki
