ADE7768 Overview
Key Features
- The only analog circuitry used in the ADE7768 is in the Σ-Δ ADCs and reference circuit
- All other signal processing, such as multiplication and filtering, is carried out in the digital domain
- This approach provides superior stability and accuracy over time and extreme environmental conditions
- The ADE7768 supplies positive-only average real power information on the low frequency outputs, F1 and F2
- These outputs can be used to directly drive an electromechanical counter or interface with an MCU
- The high frequency CF logic output, ideal for calibration purposes, provides instantaneous positive-only, real power information
- The ADE7768 includes a power supply monitoring circuit on the VDD supply pin
- The ADE7768 remains inactive until the supply voltage on VDD reaches approximately 4 V
- If the supply falls below 4 V, the ADE7768 also remains i
