NovaSensor P562 | Medical Pressure Die

Nova Sensor P562 Medical Silicon Pressure Die

The NovaSensor P562 Medical Silicon Pressure Die is a piezoresistive pressure sensor that is specifically designed for medical applications. Low linearity errors and low input and output impedance make the P562 an industry standard for disposable pressure 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 :V/V/mmHg sensitivity.

Applications

Disposable pressure transducer (DPT)
Intrauterine pressure (IUP)
Biomedical instruments
Infusion pumps

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.
