The LTC6702 is an extremely small dual comparator designed by LTC 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.
The LTC6702 is an ultra‑small dual comparator designed for battery‑powered and space‑constrained applications. It operates from 1.7 V to 5.5 V, offers a typical propagation delay of 500 ns, and draws only about 30 µA per comparator. Internal hysteresis (~4 mV) and rail‑to‑rail output capability make it suitable for high‑speed, low‑voltage designs.
The device is offered in 8‑lead SOT‑23 and 2 mm × 2 mm DFN packages. The datasheet includes absolute maximum ratings, electrical characteristics, typical performance curves, pin descriptions, and example circuits for level translation, clock regeneration, and current‑sense alarm applications.
