ADE7755ARS

The ADE7755ARS is a high-accuracy electrical energy measurement integrated circuit manufactured by Analog Devices (AD). This IC is designed to surpass the accuracy requirements of standards like IEC 1036, offering less than 0.1% error over a dynamic range of 500 to 1. It operates from a single 5V supply and consumes a typical power of 15mW, making it suitable for low-power applications.

The ADE7755ARS features on-chip power supply monitoring and creep protection. It provides active power information on frequency outputs F1 and F2, which can directly drive electromechanical counters or interface with microcontrollers. An additional CF logic output supplies instantaneous active power, useful for calibration purposes. The integrated programmable gain amplifier (PGA) in the current channel allows for the use of small shunts and burden resistors. Proprietary ADCs and DSPs ensure high accuracy across variations in environmental conditions and time.

This energy metering IC is built using a low-cost CMOS process. Its design incorporates internal phase matching circuitry and a no-load threshold to prevent creep when no load is present. The ADE7755ARS is suitable for applications requiring precise energy measurement and monitoring.
