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

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.
