DESCRIPTION

Tiny Micropower,

Low Voltage

Dual Comparators

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.
