GENERAL DESCRIPTION
The ADCMP380 is an ultralow power voltage comparator with internal reference suitable for use in general-purpose applications. The ultralow power consumption of this device makes it suitable for power efficiency sensitive systems, such as battery-powered portable devices and energy meters.
The ADCMP380 is available with a 0.5 V and 1 V internal reference with ±2.2% and ±1.6% accuracy, respectively, over the full temperature range; this internal reference enables the device to monitor the node of interest accurately to 0.5 V. The enable input allows the user to hold the output low regardless of the state of the input.
