DESCRIPTION
The Silicon Microstructures SM5822 and SM5872 series of OEM integrated pressure sensors combine state-of-the-art pressure sensor technology with on-chip signal processing technology to produce an amplified, fully conditioned, multi-order pressure and temperature compensated sensor die in a low cost SO-16 plastic package.

The sensor utilizes a CMOS digital signal processor and on-chip EEPROM for storage of calibration and compensation data. This allows the device to be factory calibrated including the effects from packaging stress. It also permits multi-order temperature and pressure compensation to achieve increased accuracy compared to conventional amplified pressure systems.

The SM5822/SM5872 series pressure sensor is a factory calibrated ready-to-use sensor system. The model SM5822 is designed for operating pressure ranges from 0-5 PSI to 0-100 PSI full-scale in gauge, absolute and differential pressure configurations. The model SM5872 is designed for operating low-pressure ranges from 0-0.6 PSI up to 0-1.5 PSI full-scale for gauge differential and single-ended differential pressure applications. For both models, the sensor output is ratiometric with the supply voltage.
