Description
The NovaSensor P1300 piezoresistive pressure Sensor Die is 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 –0.2%/°C. The P1300 is available as a differential 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.” Die Height (H) No Glass 0.4 mm 33 mil 1.2 mm 93 mil 2.8 mm AAS-920-440B-06/2014 www.amphenol-sensors.com © 2014 Amphenol Corporation.
