Appendix E.
The following is taken from the MPX4115A Integrated Pressure Sensor Data sheet.
The Motorola MPX4115A series Manifold Absolute Pressure (MAP) sensor for engine control is
designed to sense absolute air pressure. Its operating pressure range is 15 to 115 kPa (2.2 to 16.7 psi)
which produces a voltage output of 0.2 to 4.8V.
Motorola’s MAP sensor, integrated on-chip, bipolar op-amp circuitry and thin film resistor network to
provide a high-output signal and temperature compensation. The small form factor and high reliability
of on-chip integration make the Motorola MAP sensor a logical and economical choice for the
automotive system designers.
Among its features:
