LM393W中文资料低功耗双电压比较器数据手册ST规格书

描述 Description

The LM193, LM293, LM393 and LM393W devices consist of two independent low voltage comparators designed specifically to operate from a single 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.

The LM393W offers additional ESD robustness of 2 kV HBM on all pins.

特性 Features

• Wide single-supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V
