Part Number: LMP91200 If the pH sensor only has two wires which I will connect to INP and VCOM what do I connect the guard to? There is not a third conductor in the pH sensor cable.
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…
Part Number: LMP91200 Other Parts Discussed in Thread: TIDA-00561 , Dear Engineer
If you look at TIDA-00561, PIN no. 2 and 3 are specified as CAL and RTDs, and RTDs are required to appear measurable. In fact, the datasheet on the LMP91200 is made of NC pin…
Part Number: LMP91200 Other Parts Discussed in Thread: LMC6492 , LMC6062 , LMP7716 , LMP7712 , LMC6482 My company currently makes a pH meter using the LMP91200, and it works very well. As part of a lifecycle management exercise, I am redesigning a the circuit…
Part Number: LMP91200 Dear,
Our customer want to use the LMP91200 for PH measurement, so he wants to know if he need use the glass electrode,complicated electrode or participate electrode.
Best regards

Part Number: LMP91200 Hi,
I am not sure if I am checking the status on the right place but what I can see on the product page is that this component status is 'active' on the other hand I can see a forum about NRND status and we got an e-mail from Farnell…
Part Number: LMP91200 Tool/software: WEBENCH® Design Tools Hello All,
I'm realizing the schematic with LMP91200 but I'm finding in the inconsistencies. In the WEBENCH I see additional peripherals like RTD, PGA, SPI which I don't see in the datasheet.…
Part Number: LMP91200 Hello All,
My customer is working on a new low-cost pH measuring device. Currently the measurement stage is done with a quadruple operational TLC2264ID in SOIC-14 package.
Customer has the problem that at 50 °C the bias current Ib…
Part Number: LMP91200 Tool/software: WEBENCH® Design Tools The datasheets readily available on the TI website show there is an I2C connection.
Datasheets on other distributor websites show the I2C is missing.
I believe there is no I2C on this product…
Part Number: LMP91200 Other Parts Discussed in Thread: TMP117 I have designed a PH sensor circuit using the LMP91200 and when airpumps or other sensors such as an EC sensor is active in the water the PH readings go way out to lunch. Is using an Digital…
