Product Summary

The HCPL-7840-500E is an isolation amplifier. It is 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-7840-500E. A differential output voltage is created on the other side of the device optical isolation barrier. The applications of the HCPL-7840-500E are Motor phase and rail current sensing, Inverter current sensing, Switched mode power supply signal isolation, General purpose current sensing and monitoring, General purpose analog signal isolation.
