NW101 series of the small size of the pressure sensor chip applications Features: 1.0 x 1.0 mm2 Operating Temperature: -40 ℃ ~ 125 ℃ range: 700KPa, 1600KPa tire pressure monitoring system for consumer electronics applications absolute pressure sensor System Product Introduction the NW101 series of products is the Wuxi satisfied Microelectronics Co., Ltd. provides diffused silicon piezoresistive pressure sensor. 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. NW101 series of products using silicon - silicon bonding technology, smaller chip size (only 1.0 x 1.0 mm2) and reduce its cost, and provide a very cost-effective advantage for our customers choose. Pin definitions circuit schematic pin number pin definitions 1 Vs + (Sub): supply voltage input terminal (substrate) Vout +: output signal positive Gnd1: ground terminal 4 Gnd2: ground terminal 5 Vout-: Output signal negative ※ Note: NW101 diffused silicon piezoresistive pressure sensor, the silicon substrate (Sub) with high potential Vs + connected therefore must ensure that the process of using the input terminal of the supply voltage (Vs +) potential is higher than the ground terminal (Gnd1 Gnd2) potential.
