The AD7755AARSRL is an energy metering IC from Analog Devices designed for single-phase power measurement applications. It delivers a 0.1% measurement error over the specified input range, making it suitable for utility-grade metering and sub-metering installations. The 390 kOhm input impedance on the voltage channel simplifies the resistive divider design for mains-level scaling.
The AD7755AARS (without the RL suffix) is a parametric peer — same single-phase meter type, 0.1% measurement error, 390 kOhm input impedance, and 24-SSOP package. The RL suffix indicates tape-and-reel packaging; the AARS variant ships in a different reel format. Both are functionally identical for the metering core.
The AD7755AARSRL is sourced through independent distribution and quoted to order against your specific BOM quantity.
