Integrated Silicon Pressure Sensor

Altimeter/Barometer Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The MPX4115 series is designed to sense absolute air pressure in an altimeter or

barometer (BAP) applications. Motorola’s BAP 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 high reliability of on–chip

integration makes the Motorola BAP sensor a logical and economical choice for

application designers.

Features

• 1.5% Maximum Error over 0° to 85°C

• Ideally suited for Microprocessor or Microcontroller–Based Systems

• Patented Silicon Shear Stress Strain Gauge

• Available in Absolute, Differential and Gauge Configurations

• Durable Epoxy Unibody Element

• Easy–to–Use Chip Carrier Option

Application Examples

• Altimeter
