Table 3. Isotek (Isabellenhütte) Four-Terminal Shunt Summary.
Note: Values in brackets are with a heatsink for the shunt.
In some applications, however, supply currents flowing
through the power-supply return path may cause offset
or noise problems. In this case, better performance may
be obtained by connecting V
the shunt resistor with two conductors, and connecting
GND1 to the shunt resistor with a third conductor for
the power-supply return path, as shown in Figure 19.
When connected this way, both input pins should be
bypassed. To minimize electromagnetic interference of
the sense signal, all of the conductors (whether two or
three are used) connecting the isolated modulator to
the sense resistor should be either twisted pair wire or
closely spaced traces on a PC board.

The 39W resistor in series with the input lead (R2) forms
a lowpass anti-aliasing filter with the 0.01µF input
bypass capacitor (C2) with a 400 kHz bandwidth. The
resistor performs another important function as well;
it dampens any ringing which might be present in the
circuit formed by the shunt, the input bypass capacitor,
and the inductance of wires or traces connecting the
two. Undamped ringing of the input circuit near the
input sampling frequency can alias into the baseband
producing what might appear to be noise at the output
of the device.
