ADE7878ACPZ

Energy Metering Overview

The ADE7878ACPZ is a high-accuracy, three-phase electrical energy measurement integrated circuit manufactured by Analog Devices Inc. It incorporates seven analog-to-digital converters (ADCs), reference circuitry, and comprehensive signal processing to perform total active, reactive, and apparent energy measurements, including fundamental and harmonic components. The device supports RMS calculations and features a serial interface with three flexible pulse outputs. Key electrical parameters include an input impedance of 400 kΩ, a supply voltage range of 2.8 V to 3.7 V, and a supply current of 20 mA. It operates within a temperature range of -40°C to 85°C and is housed in a 40-LFCSP-WQ package.

Energy Metering Feature Summary

• Integrates seven ADCs and signal processing for total and fundamental active, reactive, and apparent energy measurement
• Supports polyphase configurations including three-wire delta and four-wire wye systems
• Provides three flexible pulse outputs for direct metering indication

Energy Metering Applications

• Three-phase smart metering systems

Energy Metering Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure that the 40-LFCSP-WQ package footprint matches your PCB design guidelines before finalizing procurement orders.

Energy Metering Selection Notes

Select this component for applications requiring precise polyphase energy measurement with integrated digital signal processing. It is suitable for designs needing simultaneous active, reactive, and apparent power calculation without external microcontrollers for basic metering functions. Consider the 40-pin LFCSP package constraints during layout planning.
