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.
This document provides an overview of the Analog Devices (ADI) ADE product family, which combines data conversion technology with a fixed-function digital signal processor to perform calculations essential for electronic energy meters. The portfolio includes single-phase and polyphase products designed for stepper motor and LCD display meter designs.
The text details two main sub-families: the ADE71xx/ADE75xx series for integrated LCD meters featuring an 8052 MCU core, and pulsed output products or stepper motor display meters. Key capabilities include high accuracy exceeding IEC and ANSI standards, on-chip reference with low temperature drift, and various tamper detection options.
| Dynamic Range (Active Energy) | less than 0.1% error over a dynamic range of 500 to 1 at 25°C |
|---|---|
| Power Consumption (Single-Phase) | as low as 15 mW (typ) |
| Power Consumption (Polyphase) | 30 mW (typ) |
| Supply Voltage | Single 5 V supply |
| LCD Segments | 104-segment LCD driver |
| Temperature Drift (Reference) | 20 ppm to 30 ppm typ |
Based on HTOL tests, meter replacement is only needed every 60 years if other components have similar life expectancy.
Yes, it includes an 8052 MCU core with flash memory.
