I see this post: https://e2e.ti.com/support/amplifiers/f/amplifiers-forum/657381/lmp91200-orp-sensing-using-lmp91200-ic
Which kind of suggests the input voltage is ±500mV around VCM. But this is for device switched off only isn…
Hi Gordon Varney .
Thanks you for your support during i'm facing with my problem.
I'm will make new PCB and replace connector with BNC and test again.
If i have same problem, i will come back
Thanks and best regards.
Part Number: LMP91200 Hi team,
A customer inquired about the internal resistance of LMP91200. These two resistors are not described in the datasheet. Are the two resistors equal? Can you find its value
Part Number: LMP91200 Other Parts Discussed in Thread: INA121 Hello!
I am developing 4-channel ion meter, and plan using LMP91200 for it. The question is - how to connect 4 parts to have one common VCM output for single reference electrode and 4 ion electrodes…

I have a weird problem where both the VOCM and VOUT signal seems completely random, single-ended and differential.
The differential can range from -0,55 - 0,2 when I'm measuring…
Part Number: LMP91200 Hi Team,
In the revision history of the datasheet of LMP91200, the temperature sensor function was deleted. A customer is looking for the RTD function of this device. I have checked our signal conditioner's product page but this…
Part Number: LMP91200 Hello!
Currently the product folder of LMP91200 shows a datasheet with no SPI and RTD connection. The early datasheet (for example https://www.mouser.com/datasheet/2/282/lmp91200-20707.pdf ) contains this pins, and part number nor case…
