LT111A中文资料Voltage Comparator数据手册ADI规格书

描述 Description

Obsolete Product: Datasheet For ReferencePurposes Only. Contact Analog Devices For Replacement Product.

The LT111A is an improved version of the LM111 general purpose comparator.  These new devices offer maximum input offset voltage of 1.0mV and input offset current of 5.0nA with a maximum response time of 250ns.  The LT111A operates from a single 5V supply to ±15V supplies and can drive up to 50mA loads referred to ground or either supply. A separate output ground pin allows output signals to be isolated from analog ground.

The versatility of the LT111A is enhanced by an input stage design which allows differential input signals of up to ±30V. Offset balancing, strobe capability and the ability to \"OR\" the output is also included. These features plus LTC's advanced processing and reliability enhancements make the LT111A an ideal choice for most comparator applications. For higher performance requirements, see the LT1011. For operation up to 200°C, see LT111X data sheet.

简介

LT111A属于集成电路（IC）的比较器。由ADI制造生产的LT111A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。
