Description

The Motorola MPX4250 series Manifold Absolute Pressure (MAP) sensor for turbo boost 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 MPX4250 series sensor integrates onchip, bipolar op amp circuitry and thin film resistor networks to provide a high level analog output signal and temperature compensation. The small form factor and reliability of onchip integration make the Motorola MAP sensor a logical and economical choice for automotive system designers.
