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
