WARNING:
Due to the delicate nature of these very sensitive devices, some special handling is required . Parts are sensitive
to shock and vibration and must be handled with care. Dropping on any hard surface (bench top etc.) can destroy
the device. Note 10 "H₂O overpressure.
Specification notes:
1. Reference conditions: supply voltage, V_S = 5 V_DC, T_A = 25°C, common-mode line pressure = 0 psig, pressure applied to P2.
2. Span is the algebraic difference between the output voltage at full scale pressure and the output at zero pressure.
3. See Definition of Terms: Hysteresis - the maximum output difference at any point within the operating pressure range for
increasing and decreasing pressure.
4. Maximum difference in output at any pressure with the operating pressure range an temperature within 0°C to +50°C after:
a) 1,000 temperature cycles, 0°C to 50°C
b) 1.5 million pressure cycles, 0 psi to full-scale span
5. Slope of the best straight line from 0°C to 50°C. For operation outside this temperature, contact factory for more specific
applications information.
6. Response time for a 0 psi to full-scale span pressure step change. 10 % to 90 % rise time.
7. Long term stability over a one year period.
8. This parameter is is not 100 % tested. It is guaranteed by process design and tested on a sample basis only.
9. If the maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die
may fracture.
