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. 8 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. 9 These times do not include thermal settling and internal filter response times (330 Hz bandwidth), which may affect overal accuracy. 10 The RST line must be held low for at least 10 μs to assure a proper reset and recovery sequence. 11 The xMAGN_OUT and BARO_OUT registers update at a rate that is 1/16th that of the other output registers. 12 The sync input clock functions below the specified minimum value but at reduced performance levels.
