Manifold Absolute Pressure Sensors

On-Chip Signal Conditioned,

0.25 V to 4.9 V Output, Temperature

Compensated and Calibrated

The Motorola MPXT4100A/4101A/4105A 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

• Patented Silicon Shear Stress Strain Gauge

• Temperature Compensated Over –40°C to +125°C

• Surface Mount Package

• Ideal for Non–Automotive Applications

• Also Available in Unibody Package

Application Examples

• Manifold Sensing for Automotive Systems

The MPXT4100A/4101A/4105A series piezoresistive

transducer is a state–of–the–art, monolithic, signal con-

ditioned, silicon pressure sensor. This sensor, with its pat-

ented transducer, combines advanced micromachining

techniques, thin film metallization, and bipolar semicon-

ductor 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.
