MicroPressure MPR Series, compensated/amplified, absolute, leadless SMT long port on breakout board, with silicone gel, 0 psi to 25 psi, 24-bit digital I²C address: 0x18 output, 10% to 90% of 224 counts transfer function

  • 60 mbar to 2.5 bar | 6 kPa to 250 kPa | 1 psi to 30 psi


    The MPR Series is a very small piezoresistive silicon pressure sensor offering a digital output for reading pressure over the specified full scale pressure span and temperature range. It is calibrated and compensated over a specific temperature range for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). This product is designed to meet the requirements of higher volume medical (consumer and non-consumer) devices, commercial appliance, and industrial/HVAC applications.

Value to Customers

  • Very small form factor: Enables portability by addressing weight, size, and space restrictions; occupies less area on the PCB.
  • Wide pressure ranges simplify use.
  • Enhances performance: Output accelerates performance through reduced conversion requirements and direct interface to microprocessors.
  • Value Solution: Cost-effective, higher volume solution with configurable options.
  • Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1 requirements: Allows avoidance of thermal and mechanical damage during solder reflow attachment and/or repair that lesser rated sensors may incur; allows unlimited floor life when stored as specified (simplifying storage and reducing scrap); eliminates lengthy bakes prior to reflow, and allows for lean manufacturing due to stability and usability shortly after reflow.
  • Low power/energy efficient: Reduces system power requirements and enables extended battery life.


  • Application-specific design addresses specific application needs and challenges.
  • Digital output: Plug and play feature enables ease of implementation and system level connectivity.
  • Total Error Band: Provides true performance over the compensated temperature range, which minimizes the need to test and calibrate every sensor, thereby potentially reducing manufacturing cost; improves sensor accuracy and offers ease of sensor interchangeability due to minimal part-to-part variation.
