SDP816-125Pa Frequently Asked Questions (FAQs)

  • A symmetrical layout with a solid ground plane and a separate analog ground plane is recommended. Keep the sensor away from high-frequency components and ensure a low-impedance path to ground.
  • Calibration involves applying known pressures and recording the corresponding output voltages. A 2-point or 5-point calibration is recommended, with one point at atmospheric pressure and the other points at the minimum and maximum pressures of interest.
  • Apply power to the VCC pin first, followed by the VDD pin. This ensures that the internal voltage regulators are powered up correctly and prevents damage to the device.
  • Temperature compensation can be achieved using an external temperature sensor and a microcontroller to correct for temperature-related errors. Alternatively, use a temperature-compensated version of the sensor or a separate temperature sensor to correct for temperature effects.
  • The maximum allowable pressure range is -1 to 16 bar (gauge pressure). Exceeding this range may damage the sensor or affect its accuracy.
