The AD7751ARS is a single-phase energy metering IC from Analog Devices, part of the AD7751 series, in a 24-SSOP (0.209", 5.30mm Width) surface-mount package. The 400 kOhm input impedance sets the loading on the voltage sense divider — a higher impedance reduces power dissipation in the divider resistors, which matters for the overall meter thermal budget.
It is marked RoHS non-compliant — verify local exemptions if your BOM requires full RoHS conformance.
The AD7751AARS is a peer with the same 0.1% measurement error, 400 kOhm input impedance, and 24-SSOP package, but the supply voltage differs — check your rail before substituting.
