The ADE family of products from Analog Devices combines industry-leading data conversion technology with a fixed function digital signal processor (DSP) to perform the calculations essential to an electronic energy meter. The portfolio includes single-phase products and polyphase products for stepper motor and LCD display meter designs, with five critical measurements available: watt, V rms, I rms, VA, and VAR. With 175 million units deployed in the field, ADI has added to the portfolio the ADE71xx and ADE75xx product families that simplify energy meter design by providing all the features needed for an accurate, reliable, and fully functional energy meter with LCD display in a single IC.
