The NovaSensor P1300 Low Pressure Sensor Die are highly reliable, solid state pressure sensors, offered in a miniature 2.7 mm x 3.2 mm die. When excited with 1.5 mA, the P1300 produces a millivolt output that is proportional to input pressure. The sensor will operate with a constant voltage supply; however, the sensitivity will change –0.23%/°C. The P1300 is available as a diff erential and gauge sensor. NovaSensor’s SenStable® process provides good long-term stability and excellent repeatability. The die substrate must be connected to the positive power supply in order to maintain good long-term stability. To achieve this, +INa is connected to the sensor as well as the substrate pad, which is labeled with an “S.”
