DESCRIPTION
The LTC^®6702 is an extremely small dual comparator
designed to maximize battery life while providing both
speed and low voltage operation in applications where
board space is a premium.
These comparators operate on supplies between 1.7V and
5.5V, and have a maximum guaranteed propagation delay
of 500ns while drawing only 30μA maximum quiescent
current. Internal hysteresis desensitizes the LTC6702 to
input noise and makes it easy to use, even with slow mov-
ing signals. CMOS inputs allow the use of large source
impedances.
The LTC6702 is available in the 8-pin SOT-23 and the tiny
2mm × 2mm DFN package.
