The document provides a comprehensive overview of the ADE7880 Energy Metering IC evaluation board (UG-356). It details how to connect external transducers for 3-phase energy metering applications, including instructions for using current transformers and Rogowski coils. The guide explains the board's power supply requirements, specifically noting that it requires two domains: one for the microcontroller via USB and another for the isolated ADE7880 components.
| Device Type | 3-phase electrical energy measurement IC |
|---|---|
| ADC Technology | second-order sigma-delta (Σ-Δ) |
| Isolation Method | optically isolated |
| Communication Interface | USB-based communication with a PC |
The board requires two power supplies: an external 3.3 V supply and one provided by connecting a USB cable between a PC and the board.
Yes, current transformers or Rogowski coils can be used to sense currents for the phase and neutral inputs.
The maximum signal level permissible at the V AP , VBP, and VCP pins of the ADE7880 is 0.5 V peak.
