LM393集成電路（IC）的比較器規(guī)格書PDF中文資料

General Description

consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteris

tic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Features
