SM1491 - Gauge and Differential Pressure Sensor

Download the SM1491 datasheet PDF. This datasheet also covers the SM1291 variant, as both devices belong to the same gauge and differential pressure sensor family and are provided as variant models within a single manufacturer datasheet.

Description

The SM1X91 series are a medium pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce both digital & analog output, fully conditioned, multi-order pressure and temperature compensated outputs.

Features

  • 15 psi gauge, differential or asymmetric differential outputs.
  • Digital Accuracy: +/- 1 %FS; Analog Accuracy: +/- 1.5 %FS.
  • 16-bit digital, pressure calibrated and temperature compensated output.
  • I2C and analog output interface available.
  • Compensated temperature range: -20°C to 85°C.
  • Robust JEDEC SOIC-16 package for automated assembly.
  • Manufactured according to ISO9001 and ISO/TS 16949 standards.
