描述 Description

This device consists of four independent precision voltage comparators, which are 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 the negative rail even though operated from a single power supply voltage.

特性 Features

? Wide single supply voltage range or dual supplies for all devices: +2 V to +36 V or ±1 V to ±18 V
? Very low supply current (1.1 mA) independent of supply voltage (1.4 mW/comparator at +5 V)
? Low input bias current: 25 nA typ.
? Low input offset current: ±5 nA typ.
? Input common-mode voltage range includes negative rail
? Low output saturation voltage:250 mV typ. (IO= 4 mA)
? Differential input voltage range equal to the supply voltage
? TTL, DTL, ECL, MOS, CMOS compatible outputs

簡介

LM2901屬于集成電路（IC）的比較器。由制造生產(chǎn)的LM2901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輸入是否相同，幅度型比較器還指示兩個輸入不相同時哪個較大。它們不同于比較兩個模擬輸入幅度的器件，后者稱為線性比較器且單獨分類。
