Short-term repeatability is related to the in-run bias stability and noise density specifications. 4 The X_ACCL_LOW (see Table 24), Y_ACCL_LOW (see Table 26), and Z_ACCL_LOW (see Table 28) registers capture the bit growth associated with the user configurable filters. 5 The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant. 6 Endurance is qualified as per JEDEC Standard 22, Method A117, and measured at −40°C, +25°C, +85°C, and +125°C. 7 The data retention lifetime equivalent is at a junction temperature (TJ) of 85°C as per JEDEC Standard 22, Method A117. Data retention lifetime decreases with junction temperature. 8 These times do not include thermal settling and internal filter response times (375 Hz bandwidth), which may affect overal accuracy. 9 The parameter assumes that a ful start-up sequence has taken place, prior to initiation of the reset cycle. 10 This parameter represents the time between raising the RST line and restoration of pulsing on the DR line, which indicates a return to normal operation. 11 This parameter represents the pulse time on the RST line, which ensures initiation of the reset operation. 12 The sync input clock functions below the specified minimum value but at reduced performance levels.
