The Analog Devices ADE7755ARS is a highly accurate energy metering IC designed for monitoring and measuring real power consumption in single-phase electrical systems. Surpassing the IEC 687/1036 standards for 50 Hz and 60 Hz accuracy, it provides less than 0.1% error over a wide dynamic range of 500:1, making it suitable for precise metering in residential, commercial, and industrial applications. This device outputs average real power through its F1 and F2 frequency pins, while the high-frequency CF output enables calibration and supplies instantaneous real-power information. It includes proprietary ADC and DSP technology to maintain high performance even under varying environmental conditions and long-term usage.
The ADE7755ARS features a programmable gain amplifier in the current channel, allowing the use of small shunt or burden resistors while maintaining excellent measurement sensitivity. The logic output REVP helps detect issues such as wiring errors or negative power flow. This IC can directly drive electromechanical counters and two-phase stepper motors for energy display systems. It also integrates a precision 2.5 V reference with external override capability, on-chip power supply monitoring, and creep protection to prevent false readings at no load. Operating from a single 5 V supply and built using low-power CMOS technology, it offers a typical power consumption of just 15 mW.
