MIC7221数据手册集成电路（IC）的比较器规格书PDF

描述 Description

The MIC7211 and MIC7221 are micropower comparators featuring rail-to-rail input performance in Micrel’s IttyBitty® SOT-23-5 package. The MIC7211/21 is ideal for systems where small size is a critical consideration.The MIC7211/21 is optimized for single supply operation from 2.2V to 10V power supplies. The MIC7211 features a conventional push-pull output while the MIC7221 has an open-drain output for mixed-voltage applications with an external pull-up resistor.The MIC7211/21 benefits small battery-operated portable electronic devices where small size and the ability to place the comparator close to the signal source are primary design concerns.

特性 Features

• Small footprint SOT-23-5 package
• Guaranteed performance at 2.2V, 2.7V, 5V, and 10V
• 7µA typical supply current at 5V
• 100mA typical sink or source

简介

MIC7221属于集成电路（IC）的比较器。由制造生产的MIC7221比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。
