MAX985EUK+T 模拟比较器产品概述

一、核心参数总览

MAX985EUK+T为单路模拟比较器,核心参数覆盖精度、功耗、速度及环境适应性等关键维度:

  • 输入精度:输入失调电压(Vos)500μV、输入偏置电流(Ib)1pA、输入失调电流(Ios)0.5pA,适配高阻抗/微弱信号检测;
  • 速度特性:传播延迟(tpd)300ns、响应时间(tr)40ns,满足中等速率信号比较需求;
  • 抗干扰:滞后电压(Vhys)3mV(抑制输出震荡)、共模抑制比(CMRR)80dB(降低共模干扰);
  • 功耗与电源:静态电流(Iq)11μA(低功耗)、单电源2.5V5.5V、双电源支持1.25V2.75V/-2.75V~-1.25V,最大电源宽度6V;
  • 环境适应性:工作温度-40℃~+85℃(工业级范围)。

二、关键特性优势

1. 高精度输入适配

500μV的输入失调电压远低于普通比较器,可准确识别μV级微弱信号;1pA的超低偏置电流无需额外缓冲电路,直接适配高阻抗传感器(如光电二极管、应变片),避免信号衰减。

2. 轨到轨简化设计

输入电压覆盖电源轨(Vss至Vdd),输出电平接近电源轨(无需电平转换),尤其适合单电源低电压系统(如2.5V~5.5V),减少外围元件数量,降低系统成本。

3. 低功耗延长续航

11μA的静态电流在电池供电设备中优势显著(如无线传感器节点、便携医疗设备),配合单电源最低2.5V工作电压,可大幅延长电池使用时间。

4. 抗干扰提升可靠性

3mV滞后电压有效抑制输入噪声(如电磁干扰、电源纹波)导致的输出震荡,避免误触发;80dB共模抑制比可削弱共模信号干扰,保障复杂环境下的稳定输出。

三、输出与封装细节

  • 输出类型:推挽CMOS输出,可直接驱动TTL/CMOS逻辑电路,无需外接上拉/下拉电阻,简化外围电路设计;
  • 封装形式:SOT-23-5小型封装(尺寸约2.9mm×1.6mm),节省PCB空间,适配便携设备、小型模块等空间受限场景;
  • 引脚布局:5引脚集成电源(Vdd/Vss)、差分输入(IN+/IN-)、输出(OUT),布局简洁,便于系统集成。

四、典型应用场景

1. 电池供电便携设备

如智能手环、无线温度传感器,低功耗(11μA)延长续航,小封装节省空间,适配2.5V~5.5V单电源。

2. 工业传感器阈值检测

如压力传感器、光电传感器的信号比较,500μV失调电压保障检测精度,-40℃~+85℃宽温适配工业现场环境。

3. 低电压消费电子

如手机充电保护电路、耳机音量控制,轨到轨输出简化电平匹配,单电源2.5V~5.5V适配主流移动电源。

4. 电源电压监测

如电池欠压保护、电源纹波阈值检测,3mV滞后电压避免反复触发,高CMRR削弱电源干扰。

五、品牌与可靠性

该产品由ADI(亚德诺)/LINEAR品牌推出,采用成熟模拟工艺,符合工业级可靠性标准,可稳定应用于商业及工业场景,广泛获得市场验证。

MAX985EUK+T凭借高精度、低功耗、小封装及宽温特性,成为低电压模拟比较场景的高性价比选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
