Integrated Silicon Pressure Sensor

Manifold Absolute Pressure Sensor

On-ChipSignal Conditioned,

Temperature Compensated

and Calibrated

The Motorola 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 Motorola 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

Application Examples

• 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.
