Voltage Sensing
The HCPL-7560 Isolated Modulator can also be used to
isolate signals with amplitudes larger than its recom-
mended input range with the use of a resistive voltage
divider at its input. The only restrictions are that the
impedance of the divider be relatively small (less than 1
kW) so that the input resistance (280 kW) and input bias
current (1µA) do not affect the accuracy of the mea-
surement. An input bypass capacitor is still required,
although the 39W series damping resistor is not (the
resistance of the voltage divider provides the same
function). The low-pass filter formed by the divider re-
sistance and the input bypass capacitor may limit the
achievable bandwidth. To obtain higher bandwidth,
the input bypass capacitor (C2) can be reduced, but it
should not be reduced much below 1000 pF to maintain
adequate input bypassing of the isolated modulator.
