Integrated Silicon Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The MPX5999D piezoresistive transducer is a state–of–the–art pressure sensor

designed for a wide range of applications, but particularly for those employing a

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

transducer combines advanced micromachining techniques, thin–film metallization and

bipolar semiconductor processing to provide an accurate, high level analog output signal

that is proportional to applied pressure.

Figure 1 shows a block diagram of the internal circuitry integrated on the stand–alone

sensing chip.

Features

• Temperature Compensated Over 0 to 85°C

• Ideally Suited for Microprocessor or Microcontroller–Based Systems

• Patented Silicon Shear Stress Strain Gauge

• Durable Epoxy Unibody Element
