Operating within a supply range of 1.
7V to 5.
5V, the devices only draw 6.
5µA 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.
