Need help on selecting IC to work with SPEC Sensor

Dear Digikey Technical Support,

I am planning to develop this Carbon Monoxide sensor.

https://www.digikey.hk/en/products/detail/spec-sensors-a-division-of-interlink-electronics/110-109/6136364

However, its factory only shows a very simple example circuit. It is not enough to be an accurate commercial product.

I also heard that there are some existing ICs which are specifically designed to interface this type of electro-chemical gas sensors; so that most of the circuit design tasks can be skipped and collected into a simple commercial IC.

So, if you know one of this special IC, would you recommend to me?

Thanks for your attention.

Yours faithfully,

Timmy

If you purchase their CO evaluation modules you are entitled to recieve the schematics for there evaluation modules which would aid in their design.

The two evaluation modules:

Do these evaluation boards include the CO gas sensor unit?

Yes they come with a through hole socketed version of the CO gas sensor.
