MAX44268EWL+T

Overview

The MAX44268EWL+T is a dual comparator with an integrated reference, housed in a 9-bump WLP package measuring 1.3mm x 1.3mm. It operates on a supply voltage range of 1.8V to 5.5V and consumes 0.7µA per comparator. The device features open-drain outputs, internal filtering for RF immunity, and a 1.236V ±1% reference. Input common-mode voltage extends 200mV beyond the rails, and inputs are 6V tolerant independent of supply.
