This device can also be used for general analog signal isolation
applications requiring high accuracy, stability, and linearity
under similarly severe noise conditions.
Analog signal isolation circuit
HCPL-7840
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.
