DESCRIPTION
With dual porting, a reference measurement is possible to minimize errors due to changes in ambient pressure. Combining the pressure sensor with a signal-conditioning ASIC in a single package simplifies the use of advanced silicon micro-machined pressure sensors. The pressure sensor can be mounted directly on a standard printed circuit board and a high level calibrated pressure signal can be acquired from the digital interface. This eliminates the need for additional circuitry, such as a compensation network or microcontroller containing a custom correction algorithm. Customer-specified pressure ranges and supply voltages are available.
