Hi,
I have an LMP91000 evaluation board connected to an ADC161S626 and SPIO-4 board. I have two questions.
1. I need to configure the jumper cables, J_VDD and J_MENB on the LMP91000SDEVAL board and the jumpers VREF_SELECT, VIO_SELECT, and VA_SELECT on the ADC161S626BEB board. How and where do I do this?
2. My second question is in the driver software. The driver software requests that I select a sensor type. I will be using the LMP91000 for electrochemical measurements (I will be hooking up counter, working, and reference electrodes to CE RE and WE on the 3-Lead electrochemical cell). I will not using this or attaching a gas sensor. Do I need to have a sensor selected if the only choices are gas sensors?
Please respond.
- Thanks, Marie

I am looking to find more information on shorting jumper cables in the LMP91000.
Thanks.
Hi Marie,
regarding your first question, all the jumpers configurations of the LMP91000SDEVAL and ADC161S626BEB are explained in the user guide:
"LMP91000 Sensor AFE Evaluation Board User's Guide" - ( http://www.ti.com/litv/pdf/snau029)
Regarding your second question there are two ways to work:
1. do not select any gas sensor from the menu and manually configure the LMP91000 accordingly your electrochemical cell's requirements.
2. create a custom sensor in the gas sensor tab, and try to convert your electrochemical cell's parameters in to gas sensor parameters (sensitivity [na/ppm], bias if needed, operating range [ppm]). Then select the sensor you created. The Graphical user interface will find the best configuration of the LMP91000 which fits the sensor you created.
best regards,
