The CPS171 is a resistive absolute pressure sensor solution with a fully calibrated pressure compensated analog output for low pressure applications, such as MAP (Manifold Absolute Pressure) systems.
The CPS171 solution comprises of an ultra-small resistive MEMS pressure sensor and a conditioning ASIC for accurate pressure measurements in factory calibrated ranges for the MAP applications. An integrated sigma-delta based ADC combined with internal calibration logic provides a high level analog output signal that is proportional to the applied pressure.
