The NW102 series of applications of the pressure sensor chip Features Dimensions: 1.6 x 1.6 mm2 Operating Temperature: -40 ℃ ~ 125 ℃ range: 100KPa, 200KPa 700KPa of 1600KPa industrial / engineering control differential pressure sensor system absolute pressure sensor system Product Introduction NW102 series The product is a the diffused silicon piezoresistive pressure sensor Microelectronics Co., Ltd. Wuxi satisfied. This series of products has a millivolt-level output signal into a good linear relationship detects pressure and superior repeatability and stability, suitable for a variety of packages such as ceramic, PCB, TO tube. NW102 products bulk micromachining, mature and stable technology, provide a very cost-effective advantage for our customers choose. The definition of pin assignment and circuit principle pressure sensor chip pressure sensor chip pin No. feet-bit 1 Vout-: Output signal negative 2 Gnd1: ground terminal 3 Gnd2: grounding end 4 Vout +: output signal positive 5 Vs +: supply voltage input end Sub (Vs +): substrate when the pressure sensor front (the side of the metal lead), according to the above definition of pin output signal is positive. ※ Note: NW102 diffused silicon piezoresistive pressure sensor, the silicon substrate (Sub) with high potential Vs + connected therefore must ensure that the process of using the potential of the input terminal of the supply voltage (Vs +) above ground the end (Gnd1 Gnd2) potential .
