The recommended power-on sequence is to apply VCC first, followed by VEE. This ensures that the internal voltage regulator is properly biased before the analog circuitry is powered up.
Calibration involves applying a known pressure to the sensor and adjusting the offset and span values to match the expected output voltage. A calibration procedure is typically performed at the factory, but users can also perform calibration using a pressure source and a multimeter.
The MPX2010GP is designed to operate up to 10 times the maximum rated pressure (100 psi) for a short duration (less than 1 second) without damage. However, continuous operation above the maximum rated pressure can lead to sensor damage or degradation.
The MPX2010GP is an ESD-sensitive device. To prevent damage, handle the device by the body, avoid touching the pins, and use an ESD wrist strap or mat when handling the device. Store the device in an anti-static bag or wrap it in anti-static material when not in use.
Keep the analog and digital traces separate, use a solid ground plane, and avoid running digital traces near the sensor's analog output pins. Use a 4-layer PCB with a dedicated analog ground plane to minimize noise and interference.
