MPX4250AP 20KPa-250KPa Pressure Sensor For Non-automotive Applications

Product Description:

MPX4250AP 20KPa-250KPa Pressure Sensor For Non-automotive Applications



Features:

The MPX4250A 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 MPX4250A series piezoresistive transducer is a state-of-the-art

monolithic silicon pressure sensor designed for a wide range of applications,

particularly those employing a microcontroller or microprocessor with A/D

inputs. This transducer combines advanced micromachining techniques, thinfilm

metallization and bipolar processing to provide an accurate, high-level

analog output signal that is proportional to the applied pressure. The small

form factor and high reliability of on-chip integration make the Freescale

sensor a logical and economical choice for the automotive system engineer.
