Ready-To-Use Pressure Sensor SM5822 / SM5872

SM5822/SM5872	Theory of Operation
DESCRIPTION SM5822/5872 pressure sensors combine state of-the-art pressure sensor technology with signal conditioning to produce a fully signal conditioned, amplified, temperature compensated sensor in a SO-16 plastic package (SMD) configuration. Combining the sensor and the signal conditioning circuitry in a single package simplifies the use of advanced silicon micro machined pressure sensors. No additional components are required for obtaining an amplified high level, calibrated pressure measurement. The output signal is available at the analog output (0.5...4.5 V / 2.5 V ± 2 V ratiometric) and at the I²C-Bus-Interface. Notice: Default address value of the I²C-Bus-Interface is 9510. This value can be modified from user’s side. SM5822 pressure ranges: 0-15PSI (0-1bar) gage,differential 0-60PSI (0-4,1bar) absolute SM5872 pressure range: 0-0,6PSI (0-41mbar) gage, differential
