Product Summary
The HCPL-7840 is an Analog Isolation Amplifier. It 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 Halleffect sensors. The HCPL-7840 consists of a sigma-delta analog-to-digital converter optically coupled to a digital-to-analog converter. The applications of the HCPL-7840 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.
