Description
The HCPL-7800(A) 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-7800(A). A differential output voltage is
created on the other side of the HCPL-7800(A) optical
isolation barrier.
