Hello Amir,
To my knowledge TI does not make electrochemical sensors, although we definitely make devices for signal conditioning of such sensors. Please see this reference design as a starting point.

Part Number: HDC1080EVM Other Parts Discussed in Thread: TIDA-00854 , HDC1080 Hi Expert,
I saw HDC1080EVM connect DAP to GND. But datasheet shows don't do that.
Also find TIDA-01452 and TIDA-00854 are floating the DAP. Why EVM do that? Thanks!
Dear Charles -
Thanks for posting. We provide the schematic and layout images in the User Manual for this EVM. https://www.ti.com/lit/ug/snau121a/snau121a.pdf
It is a two layer board, so should be pretty easy to copy from that if you really want that…
Part Number: MSP430FR6989 Tool/software: Code Composer Studio Recently I bought msp430fr6989 launch pad to get started with my project. As a beginner I am trying to implement CO gas demo (Tida 00854) sensor but I dont have source code. So can you provide…
Srilatha,
AINN shouldn't be connected to ground because it is outside the input range of the PGA. The PGA is constructed similar to the front end of an instrumentation amplifier. As any amplifier, there will be limitations to the input range and…
