Dear Sirs, I want to use Your lmp91200 part to read isfet based ph sensor output voltage. I found out from Your datasheet and reference design it is foreseen for two electrode glass pH meters with guard. Isfet based ph meter is…
Part Number: LMP91200 Hi Team,
My customer says that the old LMP91200 datasheet shows the pin 2, 3 is the CAL and RTD.
The pin description defines these 2 pin to measure the Temp. and do the calibration.
But in the datasheet on ti.com, and we found it…
Part Number: LMP91200 Hi,
There are two sets of charts for bias current in the datasheet: for Device ON and Device OFF.
What does it mean Device ON/OFF ?
