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
