The repeatability specifications represent analytical projections based on the following drift contributions and conditions: temperaturehysteresis (−40°C to +85°C), electronics

drift (high temperature operating life test: +110°C,500 hours), drift from temperature cycling (JESD22, Method A104-C,Method N, 500 cycles, −55°C to +85°C), raterandom walk

(10-year projection),and broadband noise.

2

Bias repeatability describesa long-term behavior over a variety of conditions. Short-term repeatability relates to the in-run bias stability and noise density specifications.

3

The relative error assumes that the initial error, at 25°C, is corrected in the end application.

4

Specification assumes a full scale (FS) of 1000 mbar.

5

The digital input/output signals use a 3.3 V system.

6

Endurance is qualified as per JEDEC Standard 22, Method A117, measured at −40°C, +25°C, +85°C, and +125°C.

These times do not includethermal settling and internal filter responsetimes, which may affect overall accuracy.

9

The RST line must be in a low state for at least 10 μs to assure a proper reset initiation and recovery.

10

Device functionsat clock rates below 0.7kHz, butat reduced performance levels.

11

Supply current transients can reach 600 mA during initial start up or reset recovery.
