Integrated Silicon Pressure Sensor
On-Chip Signal Conditioned,
Temperature Compensated and
Calibrated
The MP3V7007 series piezoresistive transducers are state-of-the-art
monolithic silicon pressure sensors designed for a wide range of applications,
but particularly those employing a microcontroller or microprocessor with A/D
inputs. This 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

1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range.
3. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
4. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
5. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
minimum rated pressure.
6. Accuracy (error budget) consists of the following:
Linearity:
Output deviation from a straight line relationship with pressure over the specified pressure range.
Temperature Hysteresis: Output deviation at any temperature within the operating temperature range, after the temperature is cycled to
and from the minimum or maximum operating temperature points, with zero differential pressure applied.
Pressure Hysteresis:
Output deviation at any pressure within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25°C.
TcSpan:
Output deviation over the temperature range of 0° to 85°C, relative to 25°C.
TcOffset:
Output deviation with minimum rated pressure applied, over the temperature range of 0° to 85°C, relative to
25°C.
Variation from Nominal: The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS, at 25°C.
7. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to
a specified step change in pressure.
8. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized.
9. Offset Stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.
