LM393ADR 产品概述
一、产品简介
LM393ADR 是由 UMW（友台半导体）生产的双路电压比较器，采用 SOP-8 封装，输出为开路集电极（Open-Collector）。器件专为低功耗、宽电源电压范围的比较检测场景设计，具有良好的共模输入范围和快速响应能力，适用于电平检测、零交叉检测、阈值触发等多种控制与保护电路。
二、主要特性
- 双路比较器，独立输入输出，便于多路比较设计。
- 开集输出，便于与不同电平的系统或拉电阻实现互连。
- 宽电源电压范围：单电源工作 2V ～ 36V；双电源工作 ±1V ～ ±18V（Vdd - Vss 最大 36V）。
- 低静态电流（Iq）：典型 400 μA，适合低功耗应用。
- 快速响应时间（tr）：典型 1.3 μs，满足多数中速检测需求。
- 出色的输入特性：输入失调电压（Vos）约 1 mV；输入偏置电流（Ib）约 25 nA；输入失调电流（Ios）约 5 nA。
三、典型电气参数（关键参数）
- 双电源输入范围（Vee ~ Vcc）：1V ～ 18V；负电源范围：-18V ～ -1V（注：实际双电源幅度受最大电源宽度限制）。
- 最大电源宽度（Vdd - Vss）：36V。
- 输入失调电压（Vos）：1 mV（典型）。
- 输入偏置电流（Ib）：25 nA（典型）。
- 输入失调电流（Ios）：5 nA（典型）。
- 静态电流（Iq）：400 μA（器件整片静态功耗）。
- 响应时间（tr）：1.3 μs（从输入跨越阈值到输出有效变化的典型时间）。
四、封装与引脚
- 封装形式：SOP-8，便于表面贴装与自动化生产。
- 输出为开路集电极，需外接上拉电阻以形成有效的逻辑电平接口，便于与不同电平逻辑或继电驱动级联。
五、典型应用场景
- 电平比较、阈值检测、窗口比较电路。
- 过压/欠压检测、电源监控。
- 零交叉检测、相位比较与交流检测。
- 汽车电子（非极端温度）、工控、消费类电子的传感器信号前端与告警触发。
六、选型与使用建议
- 若系统对响应速度要求较高，请验证 1.3 μs 的典型值在目标负载与布线条件下能否满足；负载和上拉电阻会影响上升沿特性。
- 由于输出为开路集电极，选用合适的上拉电阻和上拉电源以兼顾速度与功耗。
- 注意电源范围与地的共模电压，LM393 对地电位附近的输入表现良好，但超出规格可能导致不稳定。
- 在高噪声环境中建议在输入端并联小电容或采用滞后（正反馈）以抑制抖动。
LM393ADR 以其宽电源范围、低功耗和双通道配置，适合在多种工控与消费电子场景中实现可靠的电平比较与检测功能。

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.
