AS8218 Overview
The AS8218 / AS8228 are highly integrated CMOS single-phase energy metering devices for fully electronic LCD meter systems. The AS8218 / AS8228 have been designed to ensure the meters full pliance with the international Standards IEC62052 and ANSI. The AS8218 / AS8228 ICs include all the functions required for conventional 1 current or 2-current anti-tamper meters.
