Reference

Barometer - MPXAZ4115A

Pitot - MPX5010DP

MAX3227

I need to order the 296-19829-1-ND MAX3227E Datasheet

MAX3221 is the wrong chip, it only does +-5V 232 signals, I will need to remove and add the MAX3227

Calculations

Op-Amp Circuit

  • Use an LM358 Op-Amp
  • 80 to 110 kilopascals » 3.125 to 4.475 Volts. 3 to 4.5 volt rate will give 77.3 to 110 KPa range.
