Notes:
(1) If output current and voltage specifications are exceeded, linearity will be degraded.
(2) If V_OQ is programmed beyond these limits, the temperature compensation may become a problem at high
temperatures. It is not recommended to program values of V_OQ below 1V or above 4V when sensitivity exceeds 100
mV/mT. Temperature instability can occur on some devices under these conditions.
(3) Bandwidth is related to the sample rate and ROUGHGAIN. Bandwidth is estimated by (sample rate / 30)
(4) Peak to Peak Noise is a function of ROUGHGAIN setting. See page 5, Peak to Peak Noise versus Sensitivity.
(5) Sensitivity drift is independent of other parameters and does not include individual tolerances (∆VOQ or ∆VOQ/∆T).
The tolerance for sensitivity ±1% of its initial value. This does not include tolerance stack-up.
(6) If the step input occurs in the middle of a sample interval, the small signal response delay will double. For
ROUGHGAIN values less than or equal to 3, response time may be limited by the slew rate.
(7) 1 mT = 10 Gauss
