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, amplified, temperature com-
pensated sensor. The sensor utilizes a digital signal processor to
allow multiorder linear correction to achieve increased accuracy
over conventional amplified 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 configured for operating pressure ranges
