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 0-60 PSI full-scale in gauge,
differential, single-ended, and absolute
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.
