DESCRIPTION
Micropower, Low Voltage,
Dual Comparator with
400mV Reference
The LT
®
6700/LT6700HV 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, 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 (36V for
LT6700HV), independent of supply voltage. The output
stage sinking capability is guaranteed to be greater than
5mA over temperature.
The three versions of this part differ by the polar-
ity of the available comparator inputs. The LT6700-1/
LT6700HV-1 has one inverting input and one noninvert-
ing input, making it suitable for use as a window com-
parator. The LT6700-2/LT6700HV-2 has two inverting
inputs and the LT6700-3/LT6700HV-3 has two nonin-
verting inputs. All versions are offered in commercial,
industrial and automotive temperature ranges.
