Description
The HCPL-7840 isolation amplifier
family was designed for current
sensing in electronic motor drives.
In a typical implementation, motor
currents flow through an external
resistor and the resulting analog
voltage drop is sensed by the
HCPL-7840. A differential output
voltage is created on the other
side of the HCPL-7840 optical
isolation barrier. This differential
output voltage is proportional to
the motor current and can be con-
verted to a single-ended signal by
using an op-amp as shown in the
recommended application circuit.
Since common-mode voltage
swings of several hundred volts in
tens of nanoseconds are common
in modern switching inverter
motor drives, the HCPL-7840
was designed to ignore very high
common-mode transient slew
rates (of at least 10 kV/碌s).
The high CMR capability of the
HCPL-7840 isolation amplifier
provides the precision and
stability needed to accurately
monitor motor current in high
noise motor control environ-
ments, providing for smoother
control (less 鈥渢orque ripple鈥? in
various types of motor control
applications.

The product can also be used for
general analog signal isolation
applications requiring high
accuracy, stability, and linearity
under similarly severe noise con-
ditions. For general applications,
we recommend the HCPL-7840
(gain tolerance of
