ADE7769 is a high-precision energy meter IC with integrated oscillator and no-load indication.
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.
| Measurement Error | 0.1 % reading typ |
|---|---|
| Operating Temperature Range | -40°C to +85°C |
| Supply Voltage | 5 V ± 5% |
| Supply Current | 5 mA max |
| Oscillator Frequency | 450 kHz nominal |
| Reference Voltage | 2.45 V nominal |
The measurement error on Channel V1 is typically 0.1% of the reading.
No, it eliminates the cost of an external crystal or resonator by using an enhanced, precise on-chip oscillator.
The device remains inactive until the supply voltage on VDD reaches approximately 4 V.
