GENERAL DESCRIPTION
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 6.5µA 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. ...
