LM239 系列 四通道 32 V 250 nA 表面贴装 低功耗 电压比较器 - QFN-16
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.
