The Current and Power Adapter extends the capabilities of Analog Discovery devices with external circuitry to enable current measurement. It allows users to visualize current, voltage, and power in DC and AC circuits. When connected to the Analog Discovery 3 through the 2x15 MTE connector and placed between the source and load, Digilent's WaveForms software can be used to visualize current, voltage, and power in DC and AC circuits.

A reference WaveForms workspace with premade calculations to determine a variety of measurements including average current, reactive power, the phase shift of current relative to voltage, and more is freely available to provide users with a set of baseline calculations that can be determined with the Current and Power Adapter.

Features: 

  • Adjustable Current and Voltage range scaling
  • Low value shunt resistor and programmable gain current sense amplifier
  • +/-25 Amp range
  • +/-25 Volt range
  • Compatible with the AD2 and AD3: Effortless Migration
    • The AD3 and AD2 share the same 2×15 header. This allows for existing workspaces using the AD2 to be quickly and easily migrated to the AD3 (and vice versa!) by simply selecting “Yes” when prompted.

  • ECCN: EAR99
  • Current and Power Adapter for the Analog Discovery
  • Custom anti-static packaging

The Resource Center for the Current and Power Adapter is the central hub of technical content for the device, and contains everything to get started and reduce mean time to test. This includes a getting started guide, documentation, tutorials, example projects and a link to technical support.

    Some minor negatives

    Posted by Bill on 22nd Apr 2024

    The price seems excessive, even for a smaller quantity run. If the jack & standoff assembly labor costs are a large portion, then sell a kit form where we spend 30 seconds attaching them? The GND terminal came loose on mine immediately and I had to fiddle with it to get it tight. None of the terminals seem proper for this PCB setup, and the underside is not protected from accidental contact with components you might have sitting on your bench. Mine arrived with a 25V MAX label but not a 25A MAX label, so I had to print my own because that is critical info for a shunt. The shunt is Vishay 10mOhms 1% 10W, so actually it should handle around 30A, but 25A seems like a reasonable safety margin for the education market. Regardless, the shunt is only about $1.60 if you need to replace it. Despite those gripes, it's a nice addition to the AD2/AD3 ecosystem and of course Digilent is a great company.
