If the external reference voltag is not used, the Vref pin should be left unconnected. 2 Offset voltage value is after removal of core hysteresis. 3 Measurement condition : Primary conductor cross sectional area is as same as through hole, and penetration with 1turn in through hole. 4 Please derate input current to avoid excessive product heating. If you input current with high frequency band. 72 Closed loop Open loop Fluxgate system Introduction
