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.","metaTitle":"AD7751AARS Single Phase Energy Metering IC, 0.1% Error","metaDescription":"ADI AD7751AARS single-phase energy metering IC with 0.1% measurement error. 5V supply, 24-SSOP package, -40°C to 85°C.

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."},{"question":"Does AD7751AARS require external components?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/AD7751AARS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/AD7751AARS when reusing this data.
