= 1.0 mA, T
A
= 25 °C to 70 °C [32 °F to 158 °F], common-mode Line pressure =
0 psig, pressure applied to P1 unless otherwise noted.
2. If the maximum pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may
fracture.
3. Sensitivity is the ratio of the output signal voltage change to the corresponding input pressure change. The sensitivity is
characterized by design and periodic production testing. This parameter in not 100% tested in production.
4. Linearity is based on best straight line fit. Hysteresis is the maximum output difference at any point within the operating
pressure range for increasing and decreasing pressure.
5. Maximum error band of the offset voltage and the error of the band of the span over the compensated temperature range,
relative to the 25 °C reading. Typical temperature coefficients for span and resistance are -2200 ppm/°C and 2200 ppm/°C,
respectively. Temperature effects on offset and span are guaranteed by design. These parameters are not 100% tested in
production.
6. Long term stability over a one year period.
7. Response time for 0 psi to full scale span pressure step change.
