The SM1XXX Series is a digital/analog pressure sensor for 15 psi with a digital, fully-conditioned in a SOIC-16 package with either dual vertical or horizontal ports. It is available in both compound gauge, differential pressure or asymmetric configurations.
With the dual porting, a vacuum gauge measurement is possible to minimize altitude errors due to changes in ambient pressure. Customer-specific pressure ranges and supply voltages are available. Shipped in sticks or tape & reel.
