The MAX71020AETI+T is a single-chip analog front-end (AFE) designed by Analog Devices for embedded energy measurement applications. It integrates a compute engine and an improved analog-to-digital converter (ADC) with 24-bit resolution.
This AFE supports highly accurate electricity measurements, including voltage, current, frequency, active, reactive, and apparent power/energy. It boasts a Wh accuracy of ±0.1% over a 2000:1 current range and operates within a line frequency range of 40Hz to 70Hz. The device also includes digital temperature compensation and an on-chip digital temperature sensor for enhanced stability.
Designed for compact solutions, the MAX71020AETI+T comes in a small 28-pin TQFN package. It features a simple SPI slave interface for host communication and low power consumption, typically less than 5mA at 3.3V. Applications include grid-friendly appliances, smart plugs, power distribution units, and building automation systems.
