DESCRIPTION
The IC of OEM integrated pressure sensor combines state-of- the-art pressure sensor technology with signal conditioning to produce a fully signal-conditioned, amplifi ed, temperature com- pensated sensor. The sensor utilizes a digital signal processor to allow multiorder linear correction to achieve increased accuracy over conventional amplifi ed pressure systems. The device is a co- integrated die. It is also available as an IC without the sensor and is therefore suitable for the use of a precision signal processor for separate sensors. The system uses an on-chip EEPROM to store the calibration data. This allows the device to be calibrated end-of-line and so to com- pensate for packaging stress and/or parametric changes due to the addition of protective gel. Sensor ID information can also be stored in the EEPROM. The chip is currently confi gured for operating pressure ranges from 350mbar FS up to 10bar (5PSI to 145PSI FS). For pressure rang- es below 350mbar (5PSI), the IC interfaces with an off-chip sensor. The range is extendable above 10bar. VDD I² C ϑ Pin Name Description
