0 to 1000 kPa (0 to 150 PSI)
On-Chip Signal Conditioned,
0.2 V to 4.7 V Output, Temperature
Compensated and Calibrated,
Silicon Pressure Sensor
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
X–ducer 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

1. TC = 25°C unless otherwise noted. Maximum Ratings apply to Case 867–08 only.
2. Extended exposure at the specified limits may cause permanent damage or degradation to the device.
3. This sensor is designed for applications where P1 is always greater than, or equal to P2.
