Overview
LT6700-1/LT6700-2/LT6700-3 Micropower, Low Voltage, Dual Comparator with 400mV Reference FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTIO Internal 400mV Reference Combined Reference Accuracy and Offset ± 1.
5% Max at 25°C Wide Supply Range: 1.
4V to 18V Specified for –40 to 125°C Temperature Range Low Quiescent Current: 6.
5µA Typ at 5V Internal Hysteresis: 6.
5mV Typ Low Input Bias Current: ±10nA Max Over-The-Top® Input also Includes Ground Open-Collector Outputs Allows Level Translation Choice of Input Polarities: LT6700-1/LT6700-2/ LT6700-3 Available in Low Profile (1mm) SOT-23 (ThinSOTTM) and 2mm × 3mm DFN Packages The LT ®6700-1/LT6700-2/LT6700-3 combine two micropower, low voltage comparators with a 400mV reference in a 6-lead SOT-23 or tiny DFN package.
Operating with supplies from 1.
4V up to 18V, these devices draw only 6.
5µA typical, making them ideal for low voltage system monitoring.
Hysteresis is included in the comparators, easing design requirements to insure stable output operation.
The comparators each have one input available externally, the other inputs are connected internally to the reference.
The comparator outputs are open collector and the output load can be referred to any voltage up to 18V, independent of supply voltage.
The output stage sinking capability is guaranteed greater than 5mA over temperature.

The LT6700-1 has one inverting input and one noninverting input, making it suitable for use as a window comparator.
The LT6700-2 has two inverting inputs and the LT6700-3 has two noninverting inputs.
