AS331中文資料comparators數(shù)據(jù)手冊(cè)Diodes規(guī)格書

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.

簡(jiǎn)介

AS331屬于集成電路（IC）的比較器。由Diodes制造生產(chǎn)的AS331比較器邏輯比較器系列產(chǎn)品用于根據(jù)以數(shù)字格式表示的信息比較結(jié)果來生成輸出；身份型比較器指示兩個(gè)輸入是否相同，幅度型比較器還指示兩個(gè)輸入不相同時(shí)哪個(gè)較大。它們不同于比較兩個(gè)模擬輸入幅度的器件，后者稱為線性比較器且單獨(dú)分類。
