Analog Devices Inc. EVAL-ADE7913EBZ

Overview

EVAL-ADE7913EBZ from Analog Devices is a dedicated evaluation kit for the ADE7913 isolated sigma-delta ADC, enabling full characterization of three-phase energy metering performance. It integrates three populated ADE7913 devices, on-board antialiasing filters (4.8 kHz corner), shunt-based current sensing, and phase-to-neutral voltage attenuation networks - all configured for direct use with a 3-phase, 4-wire wye or 3-wire delta distribution system.

For engineers reviewing the EVAL-ADE7913EBZ datasheet, EVAL-ADE7913EBZ pinout, EVAL-ADE7913EBZ application, or EVAL-ADE7913EBZ equivalent, this kit delivers LabVIEW®-based PC control, synchronized waveform sampling at 8 kHz, real-time FFT analysis (SNR, THD, SFDR), register-level access, and emissions-optimized isolated DC-DC control via EMI_CTRL configuration.

Technical Context

The EVAL-ADE7913EBZ comprises two hardware boards - the main ADE7913 evaluation board (populated with three ADE7913 ICs) and an SDP interface board - which connect to the EVAL-SDP-CB1Z Blackfin controller via 20-pin and 120-pin interfaces. Power is delivered solely through the USB cable, regulating 3.3 V for both the SDP microcontroller and all ADE7913 devices.

Analog inputs are fully conditioned: current channels use RC antialiasing filters (1 kΩ/33 nF) and ±0.03125 V_pk full-scale range at IP/IM pins; voltage channels employ matched 330 kΩ/1 kΩ resistor dividers and ±0.5 V_pk full-scale at V1P/VM pins. Isolation is maintained via dual GNDISO pins (Pin 2 and Pin 10), each serving distinct decoupling domains for VDDISO, LDO, and VREF.

FAQ

What is the primary purpose of the EVAL-ADE7913EBZ?

The EVAL-ADE7913EBZ is a complete evaluation kit for the ADE7913 isolated sigma-delta ADC, intended to validate three-phase energy metering accuracy, synchronization, and isolation integrity. It enables engineers to perform real-time waveform capture, FFT-based metrology analysis (SNR, THD, SFDR), register-level configuration, and emissions optimization - all using the included LabVIEW® software and SDP interface hardware. The EVAL-ADE7913EBZ supports both wye and delta configurations out of the box.

Does the EVAL-ADE7913EBZ require external power supplies?

No. The EVAL-ADE7913EBZ receives all required power through the USB connection to the host PC. The SDP interface board contains a 3.3 V regulator that powers both the ADSP-BF527 microcontroller on the EVAL-SDP-CB1Z and the three ADE7913 ADCs on the main evaluation board. No additional AC or DC power sources are needed for basic operation or data acquisition.

Which companion hardware is mandatory for EVAL-ADE7913EBZ operation?

The EVAL-SDP-CB1Z (System Demonstration Platform) is mandatory and must be ordered separately. It provides the USB-to-SPI bridge, ADSP-BF527 microcontroller, and firmware necessary to communicate with the three ADE7913 devices on the EVAL-ADE7913EBZ board. Without the EVAL-SDP-CB1Z, the EVAL-ADE7913EBZ cannot be controlled or acquire data - the SDP interface board included in the kit only serves as a passive interconnect between the two.

How does the EVAL-ADE7913EBZ achieve synchronized sampling across all three phases?

The EVAL-ADE7913EBZ achieves hardware-coherent sampling by configuring the Phase A ADE7913 as the master clock source (4.096 MHz crystal), driving CLKOUT to Phase B and Phase C ADE7913 devices. Software synchronizes internal counters via broadcast writes to the SYNC_SNAP register (0x01 or 0x02), and uses the Phase C DREADY signal as an interrupt trigger for aligned waveform acquisition - ensuring sub-sample timing alignment critical for accurate power factor and harmonic analysis in the EVAL-ADE7913EBZ.

Can the EVAL-ADE7913EBZ be used with microcontrollers other than the EVAL-SDP-CB1Z?

Yes. The EVAL-ADE7913EBZ evaluation board exposes a 20-pin P5 connector compatible with custom host controllers. When used without the SDP interface and EVAL-SDP-CB1Z, users must implement SPI communication, ADE7913 register mapping, clock distribution, and DREADY interrupt handling externally. All schematics, layout files, and BOM are provided in the online design resources, enabling full integration into proprietary metering platforms beyond the standard EVAL-ADE7913EBZ workflow.
