The MPR Series is a very small piezoresistive silicon pressure sensor offering a digital output for reading pressure over the full-scale pressure span and temperature range. It is calibrated and compensated over specific temperatuere ranges 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 (250,000+ units/year) medical (consumer and non-consumer) devices and commercial appliance applications.

Value to Customers

The MPR Series’ very small form factor enables portability by addressing weight, size and space restrictions. It occupies less area on the PCB and its plug and play feature enables ease of implementation and system level connectivity. The MPR Series enhances performance through reduced conversion requirements and a direct interface to microprocessors. It meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1 requirements. The MPR Series is energy efficient by reducing system power requirements and enables extended battery life.

Differentiation

The MPR Series has a digital output and comes fully calibrated, compensated and amplified. Its application-specific design addresses various application needs and challenges. It provides true performance over compensated temperature range, which minimizes the need to test and calibrate every sensor, thereby potentially reducing manufacturing cost, improving sensor accuracy, and offers ease of sensor interchangeability due to minimal part-to-part variation.
