Timing Properties

Power-up Time

The power-up time

UP is defined as the maximum time between the supply voltage reaching its operating range

and the output voltage reaching 90% of its final value (assuming pin V

OUT open and constant input pressure).

Power-up time

Response Time and Stabilization Time

The response time

R is defined as the time required by the output to change from 10% to 90% of its final value

after a specified pressure step (assuming pin V

OUT open).

The stabilization time

S is defined as the time required by the output to meet the specified accuracy after the

pressure has been stabilized (assuming pin V

OUT open).
