LMP91000: Temperature Compensation with LMP91000 for Glucose Meter Application

Tool/software:

Hi,

We are currently working with the LMP91000 for a glucose meter application. Using test strips, we are successfully obtaining results. Recently, we received a new batch of strips, which are counter electrode-based and operate with a positive bias polarity.

With these new strips, we have observed that the output voltage is affected by temperature variations, which is impacting the measurement accuracy. To address this, we would like to implement temperature compensation.

Could you please advise:

• Does the LMP91000 offer any built-in functionality or recommended configuration for temperature compensation?

• If not, are there any suggested external methods, reference designs, or best practices for implementing temperature compensation in this type of setup (counter electrode-based strips with positive bias polarity)?

Any guidance or recommendations you can provide would be greatly appreciated.

Thanks and regards,
Nikunj
