ADE7933ARIZ

ADE7933 is a isolated energy metering chipset for polyphase shunt meters. The ADE7933 is a isolated, 3-channel sigma-delta analogue-to-digital converters (Σ-Δ ADCs) for polyphase energy metering applications that use shunt current sensors. 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. Typical applications include shunt-based polyphase meters, power quality monitoring, solar inverters, process monitoring, protective devices, isolated sensor interfaces and industrial PLCs.

• Single 3.3V supply
• Enables shunt current sensors in polyphase energy meters and immune to magnetic tampering
• 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 TA = 25°C
• Less than 0.1% error in voltage RMS over a dynamic range of 500 to 1 at TA = 25°C
• Less than 0.25% error in current RMS over a dynamic range of 500 to 1 at TA = 25°C
• Power quality measurements including total harmonic distortion (THD)
• 20 lead SOIC package
• Operating temperature range from -40°C to 85°C
