Part Number: LMP91200 Hi,
I am designing a medical-grade pH meter that needs to pass the Level 4 ESD test. The pH electrodes have very high internal resistance, so the op amp must have a very low input bias current (the LMP91200 has an input bias current…
Part Number: LMP91200 Hello, I am trying to interface my LMP91200 to Arduino UNO R3. In what way should I connect my pins from the LMP91200 to Arduino UNO? Do I also need a special library for it? Thanks
Part Number: LMP91200 Other Parts Discussed in Thread: TIDA-00561 Tool/software: Hello,
I have been studying the reference design for LMP91200 (TIDA-00561), with particular attention to the GUARD and VCM nets. It appears, from inspecting the gerber…
Part Number: LMP91200 Hi, I would like to ask you 2 basic questions about LMP91200 as below. 1) I suppose that the input buffer opeamp can be used as general "high impedance" opamp. Is my idea correct? 2) Do you have a device which has 4 pieces…
Hi Alone173,
Alone173 said: Are you continuing to use LMP91200, but you want to low cost in some of op amp and Vref design?
=> yes, you're right.
This is my initial understanding.
To replace LMP91200 with LMP7721 or other similar op amp does not…

Part Number: LMP91200
Dear Fellow members,
I would like to build a circuit to measure Ammonia in water using Ammonia ion-selective electrode. Can you help me with a reference model/design for such a circuit? Can LMP91200 be proposed for the same?

Hi Gordon Varney - Sir,
I think you already know that The PH value depends upon the temperature of the solution so We have referred to the datasheets (LMP91200 old version) We came to know that the LMP91200 has the features to connect the temperature…
