Additional Details

The HCPL-7800-000E/500E isolation amplifier uses sigma-delta modulation technology to achieve high resolution and accuracy. It provides a differential input for common-mode noise rejection. The output is a differential analog signal that can be easily interfaced with a microcontroller or other signal processing circuitry. The device is designed to meet stringent safety standards for high-voltage isolation. It is frequently used in applications requiring precise monitoring and control of high-power circuits. An external power supply is necessary. The two versions likely represent different isolation voltage ratings.
