The ADCMP341/ADCMP343 combine two low power, low
voltage comparators with a 400mV reference in the 5-lead
SOT-23 package. Operating within a supply range of 1.7V to
5.5V, the devices only draw 6.5
μ
A typical, making them ideal
for low voltage system monitoring and portable applications.
Hysteresis is determined using three resistors in a string
configuration with the upper and lower tap points connected to
the INA_U and INA_L pins of each comparator respectively.
The state of the comparators output internally selects which pin
is connected to the comparator inputs. So a change of state in
the comparator output will result in one of the inputs being
switched in to the comparator and the other being switched
out. This will provide the user with a fully flexible and simple
method of setting the hysteresis. Although there are two pins
available on each comparator, there is only actually one input
available externally at any one time, the other inputs are
connected internally to the reference.
The comparator outputs are open drain with the output stage
sinking capability guaranteed greater than 5mA over
temperature. The ADCMP341 have noninverting inputs and
the ADCMP343 have inverting inputs. Available in
commercial, industrial and automotive temperature ranges.
