Technical Data
Integrated Silicon Pressure Sensor
On-Chip Signal Conditioned,
Temperature Compensated and
Calibrated
The MPXV7025G series piezoresistive transducer is a state-of-the-art
monolithic silicon pressure sensor designed for a wide range of applications, but
particularly those employing a microcontroller or microprocessor with A/D inputs.
This patented, single element transducer combines advanced micromachining
techniques, thin-film metallization, and bipolar processing to provide an accurate,
high level analog output signal that is proportional to the applied pressure.
Features
• 5.0% Maximum Error Over 0° to 85°C
• Ideally Suited for Microprocessor or Microcontroller-Based Systems
• Temperature Compensated Over –40° to +125°C
• Thermoplastic (PPS) Surface Mount Package
• Patented Silicon Shear Stress Strain Gauge
• Available in Differential and Gauge Configurations
Typical Applications
• Respiratory Systems
• Process Control
• Patient Monitoring
• Remote Monitoring Devices

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Freescale designates the two sides of the pressure sensor
as the Pressure (P1) side and the Vacuum (P2) side. The
Pressure (P1) side is the side containing fluorosilicone gel
which protects the die from harsh media. The MPX pressure
sensor is designed to operate with positive differential
pressure applied, P1 > P2.
The Pressure (P1) side may be identified by using the
table below:

MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS
Surface mount board layout is a critical portion of the total
design. The footprint for the surface mount packages must be
the correct size to ensure proper solder connection interface
between the board and the package. With the correct
footprint, the packages will self align when subjected to a
solder reflow process. It is always recommended to design
boards with a solder mask layer to avoid bridging and
shorting between solder pads.
