The 16-bit sensitivity shown reflects the register that contains the upper 16 bits of the sensor output. Divide this number by 2 for every bit added to this resolution in downstream processing routines. 2 The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant. 3 RST and CS pins are connected to the VDD pin through 10 kΩ pull-up resistors. 4 Endurance is qualified as per JEDEC Standard 22, Method A117, and measured at −40°C, +25°C, +85°C, and +125°C. 5 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. 6 These times do not include thermal settling and internal filter response times (330 Hz bandwidth), which may affect overal accuracy. 7 The 0.7 kHz lower limit is established to support Nyquist sampling criteria for the 330 Hz sensor bandwidth. 8 During startup, the power supply current increases and experiences transient behaviors for a period of 400 µs. The peak current during the 400 µs transient period can reach 1500 mA. Rev.
