Melexis Inc. reserves the right to make changes without further notice to any products herein to improve reliability, function, or design. Melexis does
not assume any liability arising from the use of any product or application of any product or circuit described herein.
Notes:
(1) If output current and voltage specifications are exceeded, linearity will be degraded.
(2) If VOQ is programmed beyond these limits, the temperature compensation may become a problem at high tem-
peratures. It is not recommended to program values of VOQ below 1V or above 4V when sensitivity exceeds 100
mV/mT. Temperature instability can occur on some devices under these conditions.
(3) Bandwidth is inversely proportional to ROUGHGAIN.
(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 (
∆VOQor ∆VOQ/∆T).
The tolerance for sensitivity is + 1% of its initial value. This does not include tolerance stack-up.
(6) If the impulse occurs in the middle of a sample interval, the small signal response delay will double. If a 50% to
100% impulse, slew rate may result in double or triple delay.
