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.
