Analog Devices / Maxim Integrated MAX34427 High Dynamic Range Power Accumulators

Analog Devices MAX34427 High Dynamic Range Power Accumulators are specialized current, voltage, and power monitors. The MAX34427 is used to determine the power consumption of systems. The device’s wide dynamic range (20,000:1) allows for accurate power measurement. The Analog Devices device is configured and monitored with a standard I2C/SMBus serial interface. The unidirectional current sensor offers precision and high-side operation with a low full-scale sense voltage.
