MAXQ3180-RAN+T

The MAXQ3180-RAN+T by Analog Devices is a specialized analog front-end (AFE) integrated circuit designed for precise electricity measurement in polyphase systems. It is capable of collecting and calculating various metering and power-quality parameters, including voltage, current, active, reactive, and apparent power, as well as energy (kWh) for each phase and the combined 3-phase load. This device supports 3-Phase/3-Wire and 3-Phase/4-Wire services, and measures neutral line current.

Key features include a measurement error of 0.1%, a wide operating voltage range of 2.7V to 3.6V, and a typical operating current of 8.5mA. The IC operates across a temperature range of -40°C to 85°C. It incorporates an integrated ADC capable of measuring up to seven external differential signal pairs and includes an on-chip digital temperature sensor. The MAXQ3180-RAN+T communicates via an SPI-compatible serial interface.

This IC is housed in a 28-TSSOP surface mount package. Its design facilitates accurate energy metering applications, such as 3-phase multifunction electricity meters. The device also offers features like harmonic measurement, power factor calculation, and phase sequence indication, making it a comprehensive solution for advanced metering needs.
