AS331数据手册集成电路（IC）的比较器规格书PDF

描述 Description

The AS331 consists of a single precision voltage comparator with a typical input offset voltage of 1.0mV and high voltage gain. It is specifically designed to operate from a single power supply over wide range of voltages. Operation from split power supply is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. The AS331 is available in standard SOT-23-5 package.
