Integrated Silicon Pressure Sensor

for Manifold Absolute Pressure

Applications

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The Motorola MPX4200A 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 MPX4200A series sensor integrates on–chip, 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 on–chip integration make the

Motorola MAP sensor a logical and economical choice for automotive system designers.

Features

• Specifically Designed for Intake Manifold Absolute Pressure Sensing in Engine

Control Systems

• Patented Silicon Shear Stress Strain Gauge

• Temperature Compensated Over –40° to +125°C

• Offers Reduction in Weight and Volume Compared to Existing Hybrid Modules

• Durable Epoxy Unibody Element

Application Examples

• Manifold Sensing for Automotive Systems

• Ideally suited for Microprocessor or Microcontroller–Based Systems

• Also ideal for Non–Automotive Applications
