DESCRIPTION
The LT
voltage comparator with a 400mV reference in a tiny DFN
package. Operating with supplies from 1.4V up to 18V,
these devices draw only 6.5μA, making them ideal for
low voltage system monitoring. Hysteresis is included in
the comparator, ensuring stable operation.
The comparator has one input available externally while
the other input is connected internally to the reference. The
comparator output is open collector and the output load
can be referred to any voltage up to 18V independent of
supply voltage. The output stage has a guaranteed current
sink capability of more than 5mA over temperature.
The two versions of this part differ by the polarity of the
available comparator input. The LT6703-2 has an inverting
input and the LT6703-3 has a noninverting input. Both
versions are offered in commercial, industrial and automo-
tive temperature ranges.
