Input glitch immunity Available in a 1.46 mm 0.96 mm WLCSP Operational temperature range: 40C to +85C APPLICATIONS Portable/battery-operated equipment Battery monitors Energy harvesting GENERAL DESCRIPTION The ADCMP380 is an ultralow power voltage comparator with The ADCMP380 is available in a 6-ball, 1.46 mm 0.96 mm internal reference suitable for use in general-purpose applications. WLCSP and is specified over the temperature range of 40C The ultralow power consumption of this device makes it suitable to +85C. for power efficiency sensitive systems, such as battery-powered Table 1. Selection Table portable devices and energy meters. Part No. Reference Voltage (V) Output The ADCMP380 is available with a 0.5 V and 1 V internal ADCMP380-1 1 Open-drain reference with 2.2% and 1.6% accuracy, respectively, over the ADCMP380-2 0.5 Open-drain 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. Rev. B Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
