1. All values measured at 25ºC and 5 V excitation, unless otherwise

noted. Samples from each wafer are used to verify bridge resistance,

offset, span, linearity and die performance in the temperature range

between 0ºC and 70ºC.

2. Backside burst pressure and operating temperature for sensor utilizing

P1905 die can be lower than corresponding parameters for the die.

3. Typical span is equal to 160 mV at 300 psi.

4. Best fit straight line.

5. Between 0ºC and 70ºC.

6. Typical value.

Shipping and Handling

All wafers are shipped in protective containers. The

wafers are sawn on sticky tape. All wafers are electrically

probed and visually inspected. Electrical and visual rejects

are marked with ink dots. Each wafer has the following

information: part number, lot number, wafer number, and

the number of good parts.

Warrants

material and workmanship for 12 months from the date

of shipment. Products not subjected to misuse will be

repaired or replaced. NovaSensor reserves the right to

make changes without further notice to any products

herein. NovaSensor makes no warranty, representation or
