Frequently Asked Questions
What accuracy class does ADE7762ARWZ support and over what dynamic range?
The ADE7762ARWZ achieves active energy measurement accuracy better than 0.1% error over a dynamic range of 500:1, meeting IEC 62053-22 Class 0.5S requirements. Its 16-bit on-chip ADCs maintain linearity from full-scale current down to 0.2% of rated current, enabling accurate metering from light-load to heavy-load conditions.
How does the CF pulse output of ADE7762ARWZ simplify energy meter calibration?
The CF (calibration frequency) output of ADE7762ARWZ generates a high-frequency pulse train proportional to instantaneous real power, with a rate up to 14 kHz at full load. This allows factory calibration by counting CF pulses against a reference watt-hour standard over a fixed time window, eliminating the need for digital interface calibration routines.
Which metering configurations does ADE7762ARWZ support and how many current inputs are available?
The ADE7762ARWZ supports 2-wire single-phase, 3-wire two-phase, and 3-wire three-phase delta metering configurations using its 2 voltage and 2 current input channel pairs. This covers the most common poly-phase residential and commercial tariff metering topologies without requiring external multiplexing.
What supply voltage does ADE7762ARWZ require and is it compatible with 5 V meter designs?
The ADE7762ARWZ operates from a single 5 V ± 5% supply (4.75 V to 5.25 V), drawing approximately 25 mA typical supply current. It is directly compatible with 5 V power supply designs common in residential energy meters and does not require a 3.3 V regulator, simplifying BOM and reducing total meter power consumption.
