ADCMP671集成電路（IC）的比較器規(guī)格書PDF中文資料

ADCMP671屬于集成電路（IC）的比較器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的ADCMP671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。

GENERAL DESCRIPTION

The ADCMP671 voltage monitor consists of two low power, high accuracy comparators and reference circuits. It operates on a supply voltage from 1.7 V to 5.5 V and draws 17 μA maximum, making it suitable for low power system monitoring and portable applications. The part is designed to monitor and report supply undervoltage and overvoltage fault. The low input bias current and voltage reference allows resistor adjustable UV and OV threshold down to 400 mV.
