Dear team,
My customer is very interesting in the LMP91200.
The pH sensor connect to the LMP91200 and the INA116, and they look some difference in below figures(left: LMP91200; right: INA116 ).
By using the same pH sensor…
-
Is the INP connection the same as IN+ in the INA116?
-
Is the VCM connection the same as IN- in the INA116?
-
What’s the GUARD potential should be connect to(INP or Ground or …)? Is it the same as solution ground in the INA116?
Thanks~~~
