    KLN, Yes that potential LMP91200 output being so close and maybe even exceeding the reference voltage of the ADC. 3.3V VRef should be fine for LMP91200 so long as it does not exceed VDD. Yes I would be happy to review your PCB layout. Thanks -Alex Th…

    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…

    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…
