LMP91000: Has anyone configured LFO2-A4 or O2-A3 sensors with the potentiostat ?

Hi Kosala,

Can you share your schematic and configuration settings for LMP91000?

Thanks,
Ren

Thank you for the reply Ren. I have attached the settings and schematic for O2-A3. I did use these settings. Another issue I have with these settings is that the O2-A3 is a galvanic type sensor(I believe). But the settings are for a 3-lead type one.

I could not find the settings for LFO2-A4. But I used following settings.

OP_MODE: AMPEROMETRIC

FET_SHORT: Disabled

REF_SOURCE: External

INT_Z: 50% Vref

BIAS_SIGN: Negative

BIAS: 24% Vref

TIA_GAIN: 35K Ohm

RLOAD: 50Ohm 

I would like to see the schematic for the board you're actually using. Are you using a board from TI?

Are you having the same problem with both 2 pin and 3 pin sensors?

Thanks,
Ren
