LM2901B中文资料Automotive grade, low-power quad voltage comparator数据手册ST规格书

描述 Description

The LM2901B consists of four independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. It is fully specified at 5 V and 36 V single supply voltage operation, however operation from dual power supplies is also possible.

The B-grade version of the LM2901 comparators offers an increased maximum operating voltage of 40 V and improved electrical characteristics.

特性 Features
