Data retention lifetime decreases with TJ. 6 These times do not include thermal settling and internal filter response times, which may affect overal accuracy. 7 The RST line must be in a low state for at least 10 µs to ensure a proper reset initiation and recovery. 8 Sensor self test time can extend when using external clock rates that are lower than 2000 Hz. 9 Supply current transients can reach 250 mA during initial startup or reset recovery.
