Energy metering IC for dual single-phase revenue meters
The Analog Devices AD7756AN is an energy metering IC in the AD7756x series designed for two single-phase meter channels on a single chip. It delivers a measurement error of ±0.4% over the specified input range, targeting utility-grade revenue metering and submetering applications where accuracy drives compliance. The part operates from a 4.5 V to 5.5 V supply drawing 3 mA, and is specified across the industrial temperature range of -40°C to 85°C for outdoor or unconditioned environments.
What the ±0.4% measurement error means for meter design
The ±0.4% error is the worst-case accuracy over the dynamic range. The 390 kOhm input impedance sets the burden on the current sensor.
Lifecycle status and sourcing posture
The AD7756AN is listed as Active on the manufacturer's lifecycle record. There is no EOL notice or last-time-buy window on file. No official replacement or successor MPN has been issued.
