LM211M/TR 产品概述
一、产品简介
LM211M/TR 是华冠（HGSEMI）出品的单路电压比较器，封装为 SOP-8。器件支持单电源工作电压 5V ~ 30V，或双电源 ±15V，最大电源差允许值为 36V。适用于需要宽电源范围、低偏移与较快响应的通用比较场合，封装及带卷装（/TR）选项方便表面贴装与量产装配。
二、主要性能参数
- 比较器数：单路
- 输入失调电压 Vos：700 μV（典型）
- 输入偏置电流 Ib：1.7 nA
- 输入失调电流 Ios：1.7 nA
- 静态电流 Iq：2.4 mA
- 传播延迟 tpd：200 ns
- 响应时间 tr：0.2 μs
- 输出兼容：MOS、RTL、DTL、TTL、CMOS（需外部上拉配置）
- 工作温度范围：-25 ℃ ~ +85 ℃
- 封装：SOP-8（/TR 表示卷带供应）
三、功能特点
- 宽电源范围：单电源 5V~30V，或双电源 ±15V，适用于多种系统电源结构。
- 低失调与低偏置电流：Vos 700 μV 和 Ib、Ios 约 1.7 nA，适合高精度阈值检测。
- 快速响应：典型传播延迟 200 ns、响应时间 0.2 μs，适合中高速开关及脉冲处理。
- 输出兼容多种逻辑家族：通过适当上拉电阻，可驱动 MOS/TTL/CMOS 等逻辑输入。
- 低静态功耗：正常工作电流约 2.4 mA，有利于中低功耗系统设计。
四、典型应用
- 电平检测与门限比较（过压/欠压检测）
- 波形整形、零交叉检测与脉冲宽度判别
- A/D 或计数器的窗口/门控电路前端
- 逻辑电平电平移位与接口驱动（需上拉）
- 振荡器、超前/滞环比较器电路（配合正反馈实现滞环）
五、设计与使用建议
- 输出为开集电极/开漏兼容模式，需外接适当上拉电阻至目标逻辑电压，确保上拉电压 ≤ 最大电源差（36V）。上拉阻值根据负载与速度权衡选择。
- 对于噪声边缘或抖动场合，建议在正反馈端增加适量滞环（正反馈电阻），以提高抗抖动性。
- 输入端避免超出电源范围的电压，应加串联电阻或限流保护，必要时并联钳位二极管以防 ESD 或反向输入电压。
- 电源引脚应使用旁路电容（如 0.1 μF 与 10 μF 并联）贴近封装走线，以减少瞬态干扰对比较精度与响应时间的影响。
- 估算功耗时以静态电流 Iq 与工作电压乘积为参考（P ≈ Iq × Vcc），高电压条件下要注意封装散热条件。
六、封装与订购信息
- 封装形式：SOP-8（标准小外形，无铅/有铅视具体料号）
- 订货型号示例：LM211M/TR（“/TR” 常表示卷带包装，便于贴片生产）
- 建议在最终产品设计与批量采购前，向华冠或授权分销商索取最新版数据手册以核准引脚定义、电气极限与封装信息。
以上为 LM211M/TR 的概述与实用设计要点，可作为快速选型与电路实现参考。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
