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. (7) 1 mT = 10 Gauss |
