AS8228 - Highly Integrated Single Phase 2 Current Energy Metering Integrated Circuits

Description

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 compliance with the international Standards IEC62052 and ANSI.

Features

  • - - Precision single-phase, one or two current input energy measurement front-end including SigmaDelta modulators for A/D-conversion and digital signal processor (DSP). Low current consumption of 5mA, depending on MCU activity. Digital phase correction and selectable gain on both current channels for use with two current transformers (CT) or one CT and one shunt. Power-supply monitor (PSM) for power-on reset and reset when the supply voltage falls below a defined threshold. Customer programmab.
