Product details

Energy metering IC for single-phase revenue meters

The Analog Devices AD7751AARS is a single-phase energy metering IC designed for utility-grade power measurement in residential and light commercial meters. It delivers a measurement error of 0.1% across a wide dynamic range, making it suitable for revenue billing applications where accuracy must hold through light load to full-scale current. The device operates from a 4.75 V to 5.25 V supply, drawing 2 mA typical, and is specified over the industrial temperature range of -40°C to 85°C for outdoor meter enclosures.

Package and handling for the 24-SSOP

The 24-SSOP body is 5.30 mm wide with a 0.209" pitch — a standard SSOP footprint that matches the AD7751ARS and AD7755AARS variants for direct board-level swap. MSL level is not stated in this listing.

What the 0.1% error means for your BOM

The 0.1% measurement error is the headline spec. The 400 kOhm input impedance means the voltage-sense divider can use higher-value resistors without loading the mains, keeping power dissipation in the divider network low — important for meeting standby power limits in meter designs.

Frequently asked questions

When sourcing AD7751AARS, what is the closest functional second-source?

The AD7751ARS is the closest functional sibling in the same AD7751 series, sharing the same single-phase meter type, 0.1% measurement error, 400 kOhm input impedance, and 24-SSOP package. The AD7755AARS and AD7755AARSRL are also pin-compatible alternatives with a slightly different input impedance of 390 kOhm. All three are valid cross-shoppable parts for dual-sourcing.

Does AD7751AARS require external components?

Yes, like all single-phase energy metering ICs, the AD7751AARS requires external voltage dividers for the mains sensing, current shunt or CT burden resistor, and a crystal or oscillator for the timebase. The 400 kOhm input impedance allows higher-value divider resistors to keep dissipation low.
