... Caution: As most applications will use the transducer with only one single primary turn (N = 1), much of this datasheet is P written in terms of primary current instead of current linkages. However, the ampere-turns (A-t) unit is used to emphasis that current linkages are intended and applicable. Transducer simplified model ...

... Figure 31: Test connection Filtering and decoupling Supply voltage V C The fluxgate oscillator draws current pulses rate of ca. 900 kHz. Significant 900 kHz voltage ripple on V can indicate a power supply with high impedance. At these C frequencies the power supply rejection ratio is low, and the ...

... In the Ref OUT mode the 2.5 V internal precision reference is used by the transducer as the reference point for bipolar measurements; this internal reference is connected to the Ref pin of the transducer through a 680 Ohms resistor. it tolerates sink or source currents up to ± 5 mA, but the 680 Ohms resistor prevents this current to exceed these limits. ● ...
