The repeatability specifications represent analytical projections, which are based off of the following drift contributions and conditions: temperature hysteresis (−40°C

to +70°C), electronics drift (high-temperature operating life test: 85°C, 500 hours), drift from temperature cycling (JESD22, Method A104-C, Method N, 500 cycles,

−40°C to +85°C), rate random walk (10 year projection), and broadband noise.

2

Bias repeatability describes a long-term behavior, over a variety of conditions. Short-term repeatability is related to the in-run bias stability and noise density

specifications.

3

The extended pressure range is guaranteed by design.

4

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

5

Linearity errors assume a full scale (FS) of 1000 mbar.

6

The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant.

7

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

temperature.

9

These times do not include thermal settling and internal filter response times (330 Hz bandwidth), which may affect overall accuracy.

10

The RST line must be held low for at least 10 μs to assure a proper reset and recovery sequence.

The sync input clock functions below the specified minimum value but at reduced performance levels.
