Key Features
- 15 PSIA absolute pressure measurement with 0.20% static accuracy enables precise barometric and process pressure monitoring without external calibration
- 40-80mV ratiometric output with 10mV/V offset is directly compatible with standard differential ADC front-ends and signal conditioning ICs
- Compact 5.1mm x 4.1mm SMT package allows integration in space-constrained wearable medical devices and portable industrial instruments without a ported housing
Applications
NPP-301A-100A is used in barometric pressure measurement, HVAC airflow monitoring, and portable medical devices such as spirometers and infusion pumps where a non-ported absolute pressure sensor must fit on a densely populated SMT board. Its 0.20% linearity and ratiometric output simplify interface to 16-bit ADCs in data logging and environmental monitoring systems. The compact plastic SMT housing is also suitable for wearable altitude tracking devices and consumer weather stations requiring board-level pressure sensing without mechanical ports.

Frequently Asked Questions
What pressure range and accuracy does NPP-301A-100A provide for a barometric sensing design?
NPP-301A-100A measures absolute pressure up to 15 PSIA (approximately 103 kPa) with a static accuracy of 0.20%, which corresponds to a maximum error of about 0.03 PSIA across its full range. This accuracy level is sufficient for barometric altitude tracking at 1-meter resolution, HVAC duct pressure monitoring, and medical spirometry applications where pressure changes of a few Pascals must be reliably detected.
How does the 40-80mV output range of NPP-301A-100A interface with a typical microcontroller ADC?
NPP-301A-100A produces a ratiometric 40-80mV differential output with a 10mV/V offset, which requires a differential amplifier or instrumentation amplifier stage before connecting to a microcontroller's single-ended ADC input. Pairing the sensor with a 20-50x gain stage brings the 40mV full-scale span up to 0.8-2V, comfortably within the 3.3V reference range of a 12-bit or 16-bit ADC for high-resolution pressure readings.
Is NPP-301A-100A suitable for a handheld medical device where board space is limited to under 1 cm²?
Yes, NPP-301A-100A measures only 5.1mm x 4.1mm x 2.8mm in its SMT plastic package, occupying less than 0.21 cm² of PCB area. The non-ported design eliminates the need for a tube or port fitting on the board, further reducing space requirements. This makes it practical for handheld spirometers, portable oximeters, and infusion pump pressure monitoring where strict size constraints apply alongside the 0.20% accuracy requirement.
