Voltage Sensing
The HCPL-7860/HCPL-786J
Isolated Modulator can also be
used to isolate signals with
amplitudes larger than its
recommended 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
k
) so that the input
resistance (280 k
) and input
bias current (1
μ
A) do not
affect the accuracy of the
measurement. An input bypass
capacitor is still required,
although the 39
series
damping resistor is not (the
resistance of the voltage
divider provides the same
function). The low-pass filter
formed by the divider
resistance 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.
