A7840 IC-Isolation Amplifier SOP-8 Package Battery Connector DC Current and ResistanceThe Isolation Amplifier IC A7840 is intended for use in electronic motor drives to sense current. The A7840 detects the analogue voltage drop that results from motor currents flowing through an external resistor in a typical design. On the other side of the optical isolation barrier made by the A7840, a differential output voltage is produced. An op amp can be used to transform this differential output voltage, which is proportional to the motor
