About NW103 series of the small size of the pressure sensor chip applications Features: 1.8 x 1.8 mm2 Operating Temperature: -40 ° C to 150 ° C range: 150 KPa, of 400KPa industrial / engineering control consumer electronics absolute / differential pressure sensor system products NW103 Series by Wuxi City satisfied Microelectronics Co., Ltd. to provide 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. The NW103 series of products using SOI material to achieve dielectric isolation of the bridge resistance and the substrate, to improve the working temperature of the chip, suitable for high temperature applications such as boiler, electric pressure cooker environment. 2 Gnd negative definition of pin assignment and circuit principle pressure sensor chip pressure sensor chip pin No. feet-bit 1 Vout-: Output signal: grounded end 3 Vout +: output signal positive 4 Vs +: supply voltage input end when the pressure in the sensor front (one side of the metal lead), according to the above definition of pin output signal is positive.
