Motorola MPX4100A MPEXA4100A SERIES Owner's Manual User Guide
Summary
The MPX4100A series is a high-reliability Manifold Absolute Pressure (MAP) sensor designed to measure absolute air pressure in engine intake manifolds. This critical component provides accurate data for automatic engine control systems by generating a proportional voltage output signal. The accompanying datasheet details the device’s advanced technical specifications, including operational ranges, temperature stability, and electrical characteristics. It is ideally suited for automotive system designers utilizing microprocessors or microcontrollers, but its robust design also makes it valuable for various non-automotive industrial monitoring applications.

!# INTEGRATED PRESSURE SENSOR
The Motorola MPX4100A/MPXA4100A series Manifold Absolute Pressure (MAP) 15 to 115 k Pa (2.2 to 16.7 psi) sensor for engine control is designed to sense absolute air pressure within the intake 0.2 to 4.8 Volts Output 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.
The MPX4100A/MPXA4100A series piezoresistive transducer is a state–of–the–art, UNIBODY PACKAGE
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.
