ADE7868AACPZ - 3-Phase Energy Metering IC | Analog Devices
MPN： ADE7868AACPZ ✓ 啟用中ADE7868AACPZ 概覽
An energy-metering IC is a specialized analog and digital signal-processing component that converts voltage and current information into calibrated measurements, accumulated energy values, and output events. Within the broader hierarchy, the ADE7868AACPZ belongs to the energy-metering IC class, then to specialized data-conversion and power-management system ICs. Its integrated signal chain reduces the need for external analog front-end components while supporting accurate multi-phase measurement.
According to the Analog Devices ADE7868A product-page description, the device incorporates second-order sigma-delta analog-to-digital converters, a digital integrator, reference circuitry, and the processing required for fundamental and harmonic energy calculations. The ADE7868A and ADE7878A family also includes IRQ0 and IRQ1 interrupt request pins and low-power modes intended to preserve energy accumulation during tampering situations.
The package and electrical details identify the ADE7868AACPZ as a 40-pin, square, surface-mount LFCSP-WQ device. The supplied distributor results identify the package as 40-LFCSP-WQ, 6 x 6 mm. The Arrow listing further describes the package as a 40-pin LFCSP with exposed pad and tray packaging. These package details make it important to follow the Analog Devices land-pattern and exposed-pad recommendations during PCB design.
Typical applications include three-phase utility meters, industrial energy monitors, building power-management systems, submeters, power-quality instruments, and energy accumulation platforms. The serial interface allows a host controller or meter microcontroller to retrieve measurements, while flexible pulse outputs support external counting, calibration, or energy-pulse signaling.
For robust implementation, maintain the specified input-network topology, provide suitable analog filtering, and observe the exposed-pad thermal and soldering requirements. This page combines verified distributor listings, manufacturer-family information, comparison data, and practical design guidance; unavailable device-specific parameters are explicitly marked rather than estimated.

典型應用
ADE7868AACPZ 適用於 7 應用s: Three-Phase Utility Meter, Industrial Energy Monitoring, Building Power Management, Revenue-Grade Submeter, Power-Quality Instrument, Smart Energy Gateway, Energy Storage Monitoring.
Three-Phase Utility Meter
The ADE7868AACPZ fits a three-phase utility meter because it is specifically identified as a high-accuracy, three-phase electrical energy measurement IC. Its second-order sigma-delta ADCs, digital integrator, reference circuitry, and internal energy processing reduce the amount of external signal-processing hardware required. A system controller can use the serial interface to retrieve measurements, while the three flexible pulse outputs support meter output signaling. The 40-LFCSP-WQ 6 x 6 mm package also suits compact meter electronics, provided the PCB follows the exposed-pad land pattern.
推薦
Industrial Energy Monitoring
For industrial energy monitoring, the ADE7868AACPZ provides the measurement foundation for tracking electrical quantities across a three-phase supply. Its integrated ADCs and processing circuitry are useful when the design needs consistent conversion of sensed voltage and current signals into accumulated energy data. The serial interface allows a supervisory controller to read results, while pulse outputs can feed external counters or energy-management equipment. The exact input ranges, gain, accuracy, and calibration requirements must be taken from the manufacturer documentation before finalizing the analog front end.
推薦
Building Power Management
The ADE7868AACPZ is applicable to building power-management equipment that must measure multiple phases and preserve energy information for monitoring or billing functions. Its three flexible pulse outputs can expose energy events to external counting hardware, while the serial interface supports integration with a building controller. The device family’s low-power modes are specifically described as helping maintain energy accumulation during tampering situations, making the part relevant to secure metering designs. Product-level security and regulatory requirements still require separate verification.
推薦
Revenue-Grade Submeter
A revenue-oriented submeter can use the ADE7868AACPZ where three-phase energy accumulation and measurement integration are required in a compact package. Analog Devices identifies the ADE7868A family as capable of fundamental and harmonic energy processing, which supports more comprehensive measurement than a simple pulse-count-only architecture. Firmware can use the serial interface for calibration, diagnostics, and data retrieval. Before production release, validate the complete signal chain, calibration method, accuracy limits, and applicable metering regulations using the exact datasheet and test setup.
推薦
Power-Quality Instrument
The ADE7868AACPZ can serve as the energy-measurement core in a power-quality instrument that combines phase current and voltage sensing with host-based analysis. The integrated sigma-delta conversion and digital processing provide a structured foundation for energy calculations, while IRQ0 and IRQ1 allow enabled events to notify the host. The three flexible pulse outputs are useful when the instrument must expose energy pulses to external equipment. Exact bandwidth, harmonic limits, and sampling requirements are not present in the supplied data and must be verified from the official family documentation.
推薦
Smart Energy Gateway
A smart energy gateway can pair the ADE7868AACPZ with a communications controller to collect three-phase energy data and forward it to building or industrial systems. The serial interface supports integration with a host processor, while pulse outputs provide a simple hardware event path for compatible external meters. The ADE7868A family’s manufacturer-described low-power modes for tampering situations are relevant to continuously operating metering equipment. System designers should still validate electrical isolation, watchdog behavior, calibration storage, and fault-response requirements as part of the complete gateway design.
推薦
Energy Storage Monitoring
For energy-storage and power-conversion monitoring equipment, the ADE7868AACPZ can provide a metering path for three-phase electrical energy measurements. Its integrated ADCs and signal-processing blocks help organize sensed analog inputs into digital energy results, while the serial interface permits data transfer to a supervisory controller. The flexible pulse outputs can support synchronization with other measurement or control blocks. The provided data does not establish isolated sensing limits or storage-system-specific accuracy requirements, so those constraints must be verified before using the IC across high-voltage battery systems.

主要差異化特點
- Dedicated three-phase energy-metering architecture (對比ADE7868ACPZ)

設計說明
Use the Analog Devices recommended land pattern for the 40-LFCSP-WQ package and preserve the exposed-pad connection specified by the manufacturer. The verified distributor data confirms a 6 x 6 mm surface-mount package, but it does not provide the pad dimensions or thermal-via pattern. Do not infer those dimensions from the package size; obtain them from the official ADE7868A documentation before releasing the PCB.
Route voltage and current sensing connections as directed by the manufacturer and keep sensitive analog paths away from switching nodes and high-current paths. The ADE7868A uses second-order sigma-delta ADCs, so filtering, grounding, and input-network layout can affect measurement quality. Exact input ranges, component values, and bandwidth requirements are not included in the supplied data and must be taken from the datasheet.
Do not treat a related ADE78xx MPN as a confirmed drop-in replacement solely because its product description is similar. Before substituting ADE7868ACPZ, ADE7858ACPZ, or ADE7878AACPZ, verify package pinout, exposed-pad connection, electrical limits, serial protocol, supported energy quantities, and calibration behavior. The supplied comparison snippets do not establish complete compatibility.
