ADI Continues to Grow Its Low Power Comparator Portfolio with Dual Comparators that Feature Integrated Reference and Programmable Hysteresis
Lower power comparators are ideal for power sensitive applications such as battery-powered equipment. The ADCMP341 and ADCMP343 ICs combine two low power, low voltage comparators with a 400 mV reference in a tiny 5-lead SOT-23 package. Operating within a supply range of 1.7 V to 5.5 V, the devices only draw 6.5 µA 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 comparator's output internally selects which pin is connected to the comparator inputs. A change of state in the comparator output will result in one of the inputs being switched in to the comparator, while the other is switched out. This functionality provides the user with an easy method of setting the hysteresis. The comparator outputs are open-drain with the output stage sinking capability guaranteed greater than 5 mA over temperature. In addition, this IC family offers various features depending upon the design need—for example, the ADCMP341 has noninverting inputs while the ADCMP343 has inverting inputs. The devices are available in commercial, industrial, and automotive temperature ranges. For a complete listing of ADI comparators, visit www.analog.com/comparators.
