The LT1715 is an UltraFast dual comparator optimized for low voltage operation. Separate supplies allow independent analog input ranges and output logic levels with no loss of performance. The input voltage range extends from 100mV below VEE to 1.2V below VCC. Internal hysteresis makes the LT1715 easy to use even with slow moving input signals. The rail-to-rail outputs directly interface to TTL and CMOS. The symmetric output drive results in similar rise and fall times that can be harnessed for analog applications or for easy translation to other single supply logic levels. The LT1715 is available in the 10-pin MSOP package. The pinout of the LT1715 minimizes parasitic effects by placing the most sensitive inputs away from the outputs, shielded by the power rails. For a dual/quad single supply comparator with similar propagation delay, see the LT1720/LT1721. For a single comparator with similar propagation delay, see the LT1719.
The LT1715 is an UltraFast™ dual comparator optimized for low‑voltage operation. It features separate input and output supplies, rail‑to‑rail TTL/CMOS‑compatible outputs, and internal hysteresis for easy use with slow‑moving signals. The device is offered in a 10‑lead MSOP package and is suited for high‑speed differential line receivers, level translators, and window comparators.
The datasheet includes detailed electrical characteristics, absolute maximum ratings, pin assignments, test circuits, and typical performance curves. It also describes flexible power‑supply configurations and provides application notes such as a sine‑to‑square‑wave converter and high‑speed sampling circuits.
