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 HCPL7840 offers superior reliability, cost effectiveness, size and autoinsertability compared with the traditional solutions such as current transformers and Halleffect sensors. The HCPL-7840 consists of a sigma-delta analog-to-digital converter optically coupled to a digital-to-analog converter. Superior performance in design critical specifications such.
