The Motorola MPXS4115A series Manifold Absolute Pressure (MAP) sensor for
engine control is designed to sense absolute air pressure.
Motorola’s MAP sensor integrates on–chip, bipolar op amp circuitry and thin film
resistor networks 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 designer.
