Description
The HCPL-7840 isolation amplifier provides accurate, electrically isolated and amplified representations of voltage and current.
When used with a shunt resistor in the current path, the HCPL-7840 offers superior reliability, cost effectiveness, size and autoinsertability compared with the traditional solutions such as current transformers and Hall effect sensors.
