The ADE7761B is a high accuracy, fault-tolerant, electrical energy measurement IC intended for use with 2-wire distribution systems. The part specifications surpass the accuracy requirements as quoted in the IEC 62053-21 standard. The only analog circuitry used on the ADE7761B is in the 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 extremes in environmental conditions and over time. The ADE7761B incorporates a fault detection scheme similar to the ADE7751 by continuously monitoring both phase and neutral currents. A fault is indicated when the currents differ by more than 6.25%.The ADE7761B incorporates a missing neutral detection scheme by continuously monitoring the input voltage. When a missing neutral condition is detected (no voltage input), the ADE7761B continues billing based on the active current signal (see the Missing Neutral Mode section). The missing neutral condition is indicated when the FAULT pin goes high. The ADE7761B supplies average active power information on the low frequency outputs, F1 and F2. The CF logic output gives instantaneous active power information.The ADE7761B includes a power supply monitoring circuit on the VDD supply pin. Internal phase matching circuitry ensures that the voltage and current channels are matched. An internal no-load threshold ensures that the ADE7761B does not exhibit any creep when there is no load.
