Key Differentiators
- Absolute pressure measurement with 15-115 kPa range (vs MPXH6300A6U)
- Ratiometric output simplifies ADC interface (vs MPXV6115VC6U)
- SSOP-8 package with no port (vs HSCSAAN001PDAA5)
Design Notes
Place a 0.1 µF decoupling capacitor close to the VCC pin (pin 1) and a 1 µF capacitor on the output (pin 2) to filter noise. Ensure the ground pin (pin 3) is connected to a solid ground plane. Avoid routing high-speed digital traces near the sensor to minimize interference.
Do not exceed the supply voltage of 5.25 V, as this can damage the sensor. The output is ratiometric, so a stable supply is essential for accurate measurements. Also, ensure the pressure port is not blocked or contaminated, as this will affect readings.
The sensor's accuracy is specified over 0°C to 85°C. For applications outside this range, consider additional temperature compensation. The sensor's self-heating is minimal (supply current 6 mA), but ensure adequate airflow to avoid temperature gradients that could affect accuracy.
