MPX4100A typical application circuit shown in the figure, MPX4100A to monitor pipeline pressure. It uses the 5V power supply, C1 and C2 as power supply decoupling capacitors. C3 to denoising the output capacitor. Integrated Silicon Pressure Sensor (ISP) first by the output voltage A / D converter into a digital number, and then sent to the microprocessor (µP) to calculate the measured pressure value. To simplify the circuit can be applied with A / D converter, microcontroller, such as Motorola MC68HC05-based microcontroller company.
