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

temperatures. 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 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.
