1Motorola Sensor Device Data $$   ##% # $$  $ ##% #  !  $  !$% !#$  $ 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 ?
