HCPL-7800

Isolation amplifier designed for current sensing and voltage sensing in electronic motor drives. The product can also be used for general analogue signal isolation applications requiring high accuracy, stability and linearity under similarly severe noise conditions. Typical applications include motor phase and rail current sensing, inverter current sensing, switched mode power supply signal isolation, general-purpose current sensing and monitoring.
