Here is a typical simple Digital Barometer Block Diagram using MPL115A1. The MPL115A1 is an absolute pressure sensor with digital output. This circuit design features programmed calibration coefficients for host micro use; 50 kPa to 115 kPa Absolute Pressure; 2.375 V to 5.5 V Supply; 1 kPa Accuracy; Integrated ADC.


The integrated ADC provides digitized temperature and pressure sensor outputs via a SPI port.
