Analog Devices ADE7769 Energy Metering IC Datasheet
The ADE7769 is a high-accuracy electrical energy metering IC designed to support the IEC62053-21 standard with less than 0.1% error. It integrates an on-chip oscillator and reference, eliminating the need for external crystals or resonators to reduce system cost. The device features proprietary Sigma-Delta ADCs and DSPs for high accuracy over large variations in environmental conditions.

Questions answered in these manuals
What is the measurement error of the ADE7769?
The measurement error on Channel V1 is typically 0.1% of the reading.
Does the ADE7769 require an external crystal?
No, it eliminates the cost of an external crystal or resonator by using an enhanced, precise on-chip oscillator.
What does the CF output indicate during a no‑load condition?
The CF logic output stays high when the ADE7769 is under the no‑load threshold, providing a no‑load indication.
How does the ADE7769 signal negative power detection?
The REVP output goes high when negative power is detected, i.e., when the phase angle between voltage and current exceeds 90°.
When does the ADE7769 become active with respect to its supply voltage?
The device remains inactive until the supply voltage on Vpp reaches approximately 4 V; normal operation requires Vop of 5 V ±5%.
How many pins does the ADE7769 have and what package is used?
The ADE7769 is supplied in a 16‑lead narrow‑body SOIC package.
