The Honeywell Precision Altimeter (HPA) is the same as the HPB but with an altimeter pressure range. They share a datasheet.
Pressure Range: 0 – 17.6 psia
Compensated Temperature Range: -40°C to 85°C
Input: 5.5-30V DC
Output Options: RS-232, RS-485, or low-power TTL.
For use with non-corrosive, non-condensing gasses only.
