ADE7923ARWZ-RL General Description

The ADE7978, the ADE7933/ADE7932, and ADE7923 form achipset dedicated to measuring 3-phase electrical energy usingshunts as current sensors.The ADE7933/ADE7932 are isolated, 3-channel sigma-deltaanalog-to-digital converters (Σ-Δ ADCs) for polyphase energymetering applications that use shunt current sensors.

Key Features

Enables shunt current sensors in polyphase energy meters
Immune to magnetic tampering
Highly accurate; supports EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22, IEC 62053-23, ANSI C12.20, and IEEE 1459 standards
Compatible with 3-phase, 3- or 4-wire (delta or wye) meters and other 3-phase services
Computes active, reactive, and apparent energy on each phase and on the overall system
Less than 0.2% error in active and reactive energy over a dynamic range of 2000 to 1 at T_A = 25°C
Less than 0.1% error in voltage rms over a dynamic range of 500 to 1 at T_A = 25°C
Less than 0.25% error in current rms over a dynamic range of 500 to 1 at T_A = 25°C
Power quality measurements including THD
Single 3.3 V supply
