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.

The ADCMP380 is available in a 6-ball, 1.46 mm × 0.96 mm

WLCSP and is specified over the temperature range of −40°C to

+85°C.
