I am wanting to develop a circuit that accurately measures 15 Omron 2SMPP-03 sensors within its full range of -50KPA to 50KPA. Could someone give me a head start or refer me to some information on how to design an applicaiton circuit that conditions + measures 15 of these reliably at the same time?

I understand the sensors needs to be driven by a constant current source but there is not much information or any examples online or in the datasheet.

Thanks

Here is a link to an application note for this part... https://omronfs.omron.com/en_US/ecb/products/pdf/en_a283_e1_01.pdf

Once you can work with one of them you can use a multiplexer of some sort to read as many of them as necessary.
