We need to design a Handheld Oxygen Analyzer, which can read the oxygen purity / flow/ etc

Dear Pramod - the LMP91000 plus an O2 sensor from a vendor like CityTech, Alphasense, Spec Sensors or others would be a good starting point for your design.

Dear Pramod -

there is an EVM for the LMP91000 (on the product page, https://www.ti.com/product/LMP91000#design-development) and there are several reference designs, one of which was removed from the web, but you can see attached document which has schematic for you to reference.SNOA922.pdf

here also is a reference design done by our Ultrasonic sensing MCU team which may be of use as a reference, if you can incorporate a tube and airflow ==> https://www.ti.com/lit/an/slaa976/slaa976.pdf

Further - Spec Sensors has a very nice compact EVM which has design files available - they use a PIC MCU (vs MSP430) and a competitive %RH and temp sensor - you could use that as reference and replace with MSP430 (for MCU) and HDC2010, HDC2080, HDC2021 or HDC2022 (for %RH and temp sensor) https://www.spec-sensors.com/product-category/gas-sensor-developer-kits/
