Application information
Filtering and decoupling
Supply voltage V C
The fluxgate oscillator draws current pulses of up to 30 mA at
a rate of ca. 900 kHz. Significant 900 kHz voltage ripple on
V C can indicate a power supply with high impedance. At these
frequencies the power supply rejection ratio is low, and the rip-
ple may appear on the transducer output V OUT and reference
V REF . The transducer has internal decoupling capacitors, but in
the case of a power supply with high impedance, it is advised
to provide local decoupling (100 nF or more, located close to
the transducer)
Output V OUT
The output V OUT has a very low output impedance of
typically 2 Ohms; it can drive 100 pF directly. Adding series
Rf = 100 Ohms allows much larger capacitive loads. Empirical
evaluation may be necessary to obtain optimum results.
The minimum load resistance on V OUT is 1 kOhm.
Total Primary Resistance
The primary resistance is 0.72 m ? per conductor
In the following table, examples of primary resistance
according to the number of primary turns
Reference V REF
Ripple present on the reference output can be filtered with a
low value of capacitance because of the internal 680 Ohm
series resistance. The maximum filter capacitance value is
1 μF
