Integrated Silicon Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The MPX5050 series piezoresistive transducer is a state–of–the–art monolithic silicon

pressure sensor designed for a wide range of applications, but particularly those

employing a microcontroller or microprocessor with A/D inputs. This patented, single

element transducer combines advanced micromachining techniques, thin–film metalliza-

tion, and bipolar processing to provide an accurate, high level analog output signal that

is proportional to the applied pressure.

Features

• 2.5% Maximum Error over 0° to 85°C

• Ideally suited for Microprocessor or Microcontroller–Based Systems

• Temperature Compensated Over – 40° to +125

• Patented Silicon Shear Stress Strain Gauge

• Durable Epoxy Unibody Element

• Easy–to–Use Chip Carrier Option
