Technical Data
Integrated Silicon Pressure Sensor
Manifold Absolute Pressure Sensor
On-Chip Signal Conditioned,
Temperature Compensated
and Calibrated
The MPX4100 series Manifold Absolute Pressure (MAP) sensor for engine
control is designed to sense absolute air pressure within the intake manifold. This
measurement can be used to compute the amount of fuel required for each
cylinder. The small form factor and high reliability of on-chip integration makes
the MAP sensor a logical and economical choice for automotive system
designers.
Features
• 1.8% Maximum Error Over 0° to 85°C
• Specifically Designed for Intake Manifold Absolute Pressure Sensing in
Engine Control Systems
• Ideally Suited for Microprocessor Interfacing
• Temperature Compensated Over -40°C to +125°C
• Durable Epoxy Unibody Element
• Ideal for Non-Automotive Applications
Typical Applications
• Manifold Sensing for Automotive Systems

The MPX4100 series piezoresistive transducer is a state-
of-the-art, monolithic, signal conditioned, silicon pressure
sensor. This sensor combines advanced micromachining
techniques, thin film metallization, and bipolar semiconductor
processing to provide an accurate, high level analog output
signal that is proportional to applied pressure.
Figure 1 shows a block diagram of the internal circuitry
integrated on a pressure sensor chip.

1. Decoupling circuit shown in Figure 3 required to meet electrical specifications.
2. 1.0 kPa (kiloPascal) equals 0.145 psi.
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 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.
10. Device is ratiometric within this specified excitation range.
