Description

NovaSensor’s P562 piezoresistive pressure sensor is specifically designed for medical applications. Low lin- earity errors and low input and output impedance make the P562 an industry standard for disposable pres- sure sensor die. The sensor die is radiation tolerant for newer sterilization methods. Wire bonds are located on one side to minimize package width for DPT’s and IUP’s. Choose an open bridge wirebond configuration depending on your compensation circuit . Sensitivity can be easily scaled with external circuitry to meet the AAMI standard of 5 μV/V/mmHg sensitivity.

All values measured at 72°F (25°C) and 1 mA excitation, unless otherwise noted. 2. Zero psig. 3. Measured as the deviation at 300 mmHg from a line drawn from the output at zero pressure through the output at 100 mmHg. 4. Between 32°F and 158°F (0°C and 70°C). 5. Typical value over one year. Shipping and Handling All wafers are shipped in protective containers. The wafers are sawn on sticky tape with plastic rings. All wafers are electrically probed and visually inspected. Samples from each wafer verify offset , full-scale output , and linearity. Electrical rejects are inked with red dots. Visual rejects are inked with blue dots. Each wafer will have the following information: Lot number, wafer number, device number, and the number of good dice. Warranty NovaSensor warrants its products against defects in material and workmanship for 12 months from the date of shipment . Products not subjected to misuse will be repaired or replaced.
