Integrated Silicon Pressure Sensor
On-Chip Signal Conditioned,
Temperature Compensated
and Calibrated
The MPX5100/MPXV5100 series piezoresistive transducer is a state-ofthe-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.

• 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

• TcSpan:Output deviation over the temperature range of 0° to 85°C, relative to 25°C.
• TcOffset:Output deviation with minimum 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 V
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.

ON-CHIP TEMPERATURE COMPENSATION, CALIBRATION AND SIGNAL CONDITIONING
Figure 2 shows the sensor output signal relative to pressure
input. Typical, minimum, and maximum output curves are
shown for operation over a temperature range of 0° to 85°C
using the decoupling circuit shown in Figure 4. The output will
saturate outside of the specified pressure range.
Figure 3 illustrates both the Differential/Gauge and the Absolute Sensing Chip in the basic chip carrier (Case 867). A fluorosilicone gel isolates the die surface and wire bonds from the
environment, while allowing the pressure signal to be transmitted to the sensor diaphragm.

The MPX5100/MPXV5100 series pressure sensor operating
characteristics, and internal reliability and qualification tests are
based on use of dry air as the pressure media. Media, other
than dry air, may have adverse effects on sensor performance
and long-term reliability. Contact the factory for information regarding media compatibility in your application.
Figure 4 shows the recommended decoupling circuit for interfacing the output of the integrated sensor to the A/D input of
a microprocessor or microcontroller. Proper decoupling of the
power supply is recommended.
