ADE7758ARWZ 개요
The ADE7758 belongs to the energy-metering IC hierarchy: energy meter IC -> metering and monitoring IC -> analog and mixed-signal semiconductor -> power-management and measurement system component. Its role is to convert three-phase voltage and current signals into digital energy measurements and calibrated pulse information for utility meters, industrial energy monitors, and revenue-grade metering equipment.
The provided manufacturer description identifies second-order sigma-delta ADCs, a digital integrator, reference circuitry, and a temperature sensor. These blocks support accurate current and voltage acquisition while reducing the need for extensive external analog processing. The serial interface allows a host controller or microcontroller to retrieve measurement and calibration data, while the two pulse outputs support meter-rate signaling and external counting equipment.
Operation is specified with analog and digital supplies of 5 V ± 5%, AGND and DGND at 0 V, a 10 MHz crystal at CLKIN, and a temperature range from -40°C to +85°C. The 24-SOIC package is suitable for conventional surface-mount PCB assembly. Exact input-current, voltage, accuracy, calibration, and electrical-current ratings are not included in the supplied verified excerpts, so those values must be taken from the manufacturer datasheet before design sign-off.
Typical applications include three-phase utility meters, industrial submeters, energy-quality monitoring, active and reactive energy accumulation, and systems requiring per-phase information. The two pulse outputs are useful where an external counter, display system, or data logger needs a compact energy-rate signal rather than only a serial data stream.
For implementation, preserve the specified analog and digital grounding scheme, decouple both supply domains, route the current and voltage channels for the datasheet-recommended analog layout, and account for the 10 MHz crystal requirement. This page combines the supplied manufacturer and distributor information with practical application guidance and clearly marks parameters that require datasheet verification.

일반적인 애플리케이션
ADE7758ARWZ 적합 용도: 6 애플리케이션s: Three-Phase Utility Meter, Industrial Energy Submeter, Active and Reactive Energy Accumulation, Energy-Quality Monitoring, Revenue-Grade Metering Module, Pulse-Based Energy Display.
Three-Phase Utility Meter
The ADE7758ARWZ fits a three-phase utility meter because it is explicitly designed for high-accuracy 3-phase electrical energy measurement. Its second-order sigma-delta ADCs and integrated digital processing support active, reactive, and apparent energy calculations, while the serial interface allows a meter controller to retrieve measurement data. The two pulse outputs provide a hardware energy-rate signal for a display, counter, or communications module. The implementation must maintain the specified 5 V ± 5% AVDD and DVDD rails and use the 10 MHz CLKIN crystal arrangement.
추천
Industrial Energy Submeter
For an industrial energy submeter, the ADE7758ARWZ provides a dedicated measurement front end rather than requiring a general-purpose ADC and separate metering algorithms. The device processes three-phase current and voltage information and produces energy-related results, RMS information, and per-phase data. Its serial interface supports connection to an embedded controller, while the pulse outputs can trigger an external counter or logging input. Designers should follow the official datasheet for channel filtering, grounding, calibration, and electrical limits that are not included in the supplied excerpts.
추천
Active and Reactive Energy Accumulation
The ADE7758ARWZ is appropriate for energy accumulation systems that need more than a simple RMS measurement. The supplied manufacturer description identifies active, reactive, and apparent energy measurement functions, along with RMS information and per-phase outputs. This capability allows one metering IC to support billing, load analysis, or energy-quality monitoring in a three-phase system. The serial interface can expose the computed results to a host processor, and the two pulse outputs provide a separate rate channel when the system architecture benefits from hardware accumulation.
추천
Energy-Quality Monitoring
The ADE7758ARWZ can serve as the measurement core in an energy-quality monitor that combines three-phase real-time quantities with energy totals. Its integrated sigma-delta measurement channels, RMS information, per-phase processing, and serial communications make it suitable for systems that must collect operating data for analysis or display. The two pulse outputs can support fast external counting, while the serial interface provides more flexible access to detailed measurements. Exact bandwidth, accuracy, calibration limits, and anti-alias requirements must be verified in the ADE7758 datasheet before finalizing analog signal paths.
추천
Revenue-Grade Metering Module
The ADE7758ARWZ is suited to metering modules that require a dedicated three-phase energy-measurement IC with a serial data path and pulse outputs. Its production status is identified by Analog Devices, and the verified product description positions it as a high-accuracy multifunction energy-metering device. A module designer can pair the IC with a controller, nonvolatile storage, and communication interface, then calibrate the analog channels according to the manufacturer procedure. The supplied data does not provide regulatory certification or revenue-grade approval claims, so those requirements must be established separately.
추천
Pulse-Based Energy Display
The ADE7758ARWZ supports a pulse-based energy display architecture through its two pulse outputs. One signal path can provide a rate indication to a counter, display driver, or data logger while the serial interface carries detailed measurement information to a controller. This arrangement allows a compact display system to combine a simple hardware pulse indication with richer software-based energy data. The application must account for the electrical meaning, pulse calibration, isolation, and safety requirements of the external counting hardware, none of which are specified in the supplied search excerpts.

설계 노트
Use the specified 5 V ± 5% supplies for AVDD and DVDD, and follow the manufacturer separation and decoupling recommendations. Because the supplied excerpts do not specify capacitor values or supply-current limits, do not select those values by inference; obtain them from the official ADE7758 datasheet. Keep analog and digital return-current paths controlled so clock and digital activity do not corrupt the three-phase measurement channels.
Place the 10 MHz crystal and its required load network close to CLKIN, and route the clock away from high-current three-phase switching paths. Preserve the datasheet-recommended analog input layout and maintain clean separation between AGND and DGND. The verified data identifies the clock and package but does not provide trace dimensions, so the manufacturer layout guidance is required for a production-ready PCB.
Treat the current and voltage inputs as precision analog signals and validate channel filtering, scaling, and grounding against the complete datasheet limits. The ADE7758ARWZ uses second-order sigma-delta ADCs and integrated signal processing, but the supplied excerpts do not state input bandwidth, accuracy, or common-mode limits. Confirm those values before selecting external dividers, shunts, protection components, or PCB copper geometry.
Do not substitute a related ordering code based only on the ADE7758 family name. The supplied comparison material mentions ADE7758ARWZRL, but does not establish package, pinout, or electrical equivalence to ADE7758ARWZ. For production replacement, compare the exact package drawing, every pin function, supply ratings, clock requirements, serial protocol, calibration registers, and lifecycle status.
규정 준수 정보
The supplied verified data identifies the device as a PRODUCTION Analog Devices part but does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields must be confirmed with the manufacturer before production approval.
