Analog Devices energy monitors provide accurate, board level energy measurements in addition to other key parameters. Internal accumulators provide accurate readings of charge energy and time, with the option of using a convenient internal crystal or a more accurate external crystal as a time base. The energy monitors in this portfolio offer current, voltage, power, charge, and energy readings for rails up to 100 V or beyond using an internal shunt regulator, while others provide parametric readings and convenient sense resistor monitoring of up to ±30 A rails with only 9 mA of offset (high dynamic range).
