The ADE7752AR from Analog Devices is a high-accuracy polyphase electrical energy measurement integrated circuit designed for 3-phase applications. It supports 50 Hz and 60 Hz frequencies and achieves less than 0.1% error over a dynamic range of 500 to 1. This IC is compatible with both 3-phase/3-wire delta and 3-phase/4-wire wye configurations.
Key features include on-chip power supply monitoring, creep protection, and a 2.4V reference. The ADE7752AR supplies average real power on frequency outputs F1 and F2, which can directly drive electromechanical counters or interface with an MCU. An additional high-frequency output, CF, provides instantaneous real power for calibration purposes. The logic output REVP indicates potential miswiring or negative power for each phase.
Designed for surface mounting, the ADE7752AR comes in a 24-SOIC package with a width of 7.50mm. It operates within an ambient temperature range of -40°C to 85°C and requires a typical current of 6mA. The IC utilizes proprietary ADCs and DSP for high accuracy over variations in environmental conditions and time, surpassing IEC62053-2x standard accuracy requirements.
