ADCMP670屬于集成電路（IC）的比較器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADCMP670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(dú)分類。

GENERAL DESCRIPTION

The ADCMP670 consists of two low power, high accuracy, comparator and reference circuits in a 6-lead TSOT package. The internal 400 mV reference provides the ability to monitor low voltage supplies. The device operates on a supply voltage from 1.7 V to 5.5 V and draws only 6.5 μA typical, making it suitable for low power system monitoring and portable applications. Hysteresis is included in the comparators. The comparator outputs are open-drain and the output can be pulled up to any voltage up to 5.5 V. The output stage is guaranteed to sink greater than 5 mA over temperature.
