1

The maximum range depends on the frequency of vibration.

2

Assumes that frequency flatness calibration is enabled.

3

The digital I/O signals are 5 V tolerant.

4

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

The start-up times presented reflect the time it takes for data collection to begin.

7

The RST pin must be held low for at least 15 ns.
