A recommended PCB layout is to use a ground plane under the sensor, keep the signal traces short and away from noise sources, and use a 10nF capacitor between VCC and GND to filter out noise.
Calibration involves applying known pressures and measuring the output voltage. A two-point calibration is recommended, with one point at atmospheric pressure and another at a known higher pressure. The sensor's sensitivity and offset can then be calculated.
The maximum pressure rating for the MPX4100AP1 is 100 psi (690 kPa), but it's recommended to operate within the specified range of 0-60 psi (0-414 kPa) for optimal accuracy and reliability.
Temperature compensation can be achieved by using a thermistor or thermocouple to measure temperature and applying a correction factor to the pressure reading. The datasheet provides temperature coefficients for the sensor's sensitivity and offset.
The recommended power-on sequence is to apply VCC first, followed by a delay of at least 10ms, and then apply the input voltage to the pressure port. This ensures proper initialization and reduces the risk of damage.
