MPL115A2 Frequently Asked Questions (FAQs)

  • A good PCB layout for the MPL115A2 involves keeping the sensor away from high-current carrying traces, using a solid ground plane, and minimizing the distance between the sensor and the microcontroller. A 4-layer PCB with a dedicated ground plane is recommended.
  • The MPL115A2 requires a two-point calibration process. First, apply a known pressure (e.g., atmospheric pressure) and read the output voltage. Then, apply a second known pressure (e.g., vacuum) and read the output voltage. Use these two points to calculate the sensitivity and offset of the sensor.
  • To prevent damage to the sensor, it is recommended to power on the MPL115A2 in the following sequence: VDD, then VCC, and finally the clock signal. Power off in the reverse sequence.
  • The MPL115A2 has an internal temperature sensor that can be used for temperature compensation. The temperature data can be read from the sensor and used to correct the pressure reading using the temperature coefficient provided in the datasheet.
  • The MPL115A2 can measure pressures up to 115 kPa (16.7 psi), but it is recommended to operate within the specified range of 50 kPa to 110 kPa (7.3 psi to 16 psi) for optimal accuracy.
