The MPX5050GP from NXP/Freescale is an integrated piezoresistive silicon gauge pressure sensor designed for a pressure range of 0 to 50kPa, or 0 to 7.25psi. It integrates signal conditioning, temperature compensation, and calibration circuitry to provide a high-level analog output proportional to the applied pressure.
The sensor operates from a nominal 5V supply, with a recommended supply range of 4.75V to 5.25V. At 5V, its typical output is approximately 0.2V at zero pressure and 4.7V at 50kPa, providing a typical full-scale span of 4.5V and sensitivity of 90mV/kPa.
The MPX5050GP provides a maximum total error of ±2.5% VFSS from 0°C to 85°C. Typical response time is 1ms, typical supply current is 7mA, and maximum supply current is 10mA. The device supports an operating-temperature range of -40°C to +125°C and a maximum pressure rating of 200kPa.
This model is supplied in a single-port SENSOR6F six-terminal through-hole package with a 2.54mm terminal pitch. The package body measures approximately 17.78 × 29.47 × 8.01mm. Pin 1 is the analog output, pin 2 is ground, pin 3 is the supply input, and the remaining pins are not connected.
Device performance and reliability testing are based primarily on dry air as the pressure medium. Compatibility should be verified before using liquids, corrosive gases, or other pressure media.
