Part Number: LMP91002
HI,
We are interested in using TI reference design TIDA-00854 or LMP91002, and having following questions to decide how to start the further direction.
- Which way is more reliable in performance and stable in procurement?
Is LMP91002 under main production or just in pilot status?
Is it possible to adjust the OP-AMP Gain and Offset by firmware programming without modifying the circuits like BIAS or ADC? This question is important as we proceed the certificates and approvals like SIL2, FM, EN, Ex-Proof in order not to change our hardware after the approvals.
Thank you for your kind advice in advance.
Tony
Tony,
Both options are good options. The TIDA-00854 will require a little more work and design effort to use. Basically this option is built using discrete circuitry to demonstrate how a user could build there own gas sensor circuit.
The LMP91002, is an IC level solution with the control interface built in using I2C and a single output to an ADC. This option has software to help you get up and running faster.
I prefer the LMP91002, but that is just me. The TIDA-00854 will allow you more flexibility if you need to tweak something, and the LMP91002 is more defined.
Read all of the documentation both, the knowledge from both sets of material will help to on either solution you select.

In reply to Gordon Varney:
Thank you very much, Gortdon.
It is helpful for us to know the basic difference of both solution.
We will read more documents about these two solutions.
Best regards,
