Data retention lifetime decreases with TJ. 9 These times do not include thermal settling and internal filter response times, which can affect overal accuracy. 10 The RST line must be in a low state for at least 10 μs to ensure a proper reset initiation and recovery. 11 Self test time can extend when using external clock rates that are lower than 4000 Hz. 12 Supply current transients can reach 250 mA during initial startup or reset recovery.
