Typical Application
Description
The LTC6702 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 moving signals. CMOS inputs allow the use of large source impedances.
The LTC6702 is available in the 8-pin SOT-23 and the tiny 2mm x 2mm DFN package.
