After the output signals of the two sensors have been
merged, the basic conditioning circuitry is similar to that
used for weak field measurement. The basic principles of
the electronics are described in more detail in
Chapter “Weak field measurements”; however, the figures
quoted in that example are for a compass application and
this circuit is optimized for current measurement, with the
following characteristics:

The sensitivities and ranges of the three different sensor
set-ups shown in Fig.50 are:
Set-up 1: 1.8 V/A; range: 1.1 A
Set-up 2: 1.1 V/A; range: 1.8 A
Set-up 3: 5.7 V/A; range: 0.35 A
Note: this example uses an analog circuit, to clarify the
principles of current measurement including flipping and
magnetic compensation. A large part of the functionality of
the circuitry could easily be handled by a microprocessor
(see Fig.52 for a typical circuit diagram).
