The A7800/HCPL-7800(A) isolation amplifier family was designed for current sensing in electronic motor drives. The A7800 detects the analogue voltage drop caused by motor currents flowing through an external resistor in a typical design. A differential output voltage is created on the other side of the A7800 optical isolation barrier. The motor current is proportional to the differential output voltage, which can be converted to a single-ended signal using an op-amp as shown in the proposed
