This family of devices consists of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV maximum for LM339A, LM239A, and LM139A. Each comparator has been designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common mode voltage range includes ground even though operated from a single power supply voltage. https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2020-06-05 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2021-04-01 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2021-04-18 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2021-05-23 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2021-12-06 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2022-04-14 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2022-06-11 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2022-06-23 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2024-02-14 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2024-03-15 https://elecena.pl/product/16944448/lm339dt-low-power-quad-voltage-comparator 2024-11-15
