The ADE7755 is an energy metering IC with high accuracy, low error, and multiple output interfaces. It can be used for power meters and stepper motors, and supports small values of shunt resistance in the current channel.
The ADE7755 is a high accuracy electrical energy measurement integrated circuit designed to surpass IEC 687/1036 standard requirements. It provides average real power information on low-frequency outputs F1 and F2, while the high-frequency CF output supplies instantaneous real power for calibration purposes.
The device utilizes proprietary ADCs and DSP for signal processing in the digital domain, ensuring superior stability over environmental variations. Key features include an internal 2.5V reference with a temperature coefficient of 30 ppm/°C typical, on-chip power supply monitoring, and creep protection. The ADE7755 is available in a 24-lead SSOP package.
