MicroPressure MPR Series

Pressure Ranges

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

Description

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.

Differentiation:

• 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.
