LM393(GOODWORK 固得沃克)产品概述

一、产品简介

GOODWORK(固得沃克)LM393 是一款双路比较器,适合对电压阈值进行精确判断与开关控制。器件工作于宽电源电压范围,低功耗设计并采用 SOP-8 封装,便于在各种模拟与数字混合电路中替代或集成使用。其稳定的输入特性和可观的输入偏置、失调性能使之在传感器接口、过/欠压检测、脉宽调制及门限电平转换等场景中表现可靠。

二、主要参数

  • 比较器数:双路
  • 输入失调电压 (Vos):典型 5 mV
  • 输入偏置电流 (Ib):典型 250 nA
  • 输入失调电流 (Ios):典型 50 nA
  • 静态电流 (Iq):典型 2.5 mA(每芯片)
  • 最大电源宽度 (Vdd‑Vss):36 V
  • 单电源工作电压:2 V ~ 36 V
  • 双电源工作电压 (Vee ~ Vcc):±1 V ~ ±18 V
  • 工作温度范围:0 ℃ ~ +70 ℃
  • 封装:SOP-8(表面贴装)

三、关键特性与优势

  • 宽电源电压:支持2 V 至36 V 单电源或±1 V 至±18 V 双电源,设计灵活。
  • 低静态电流:典型 Iq 2.5 mA,有利于电池供电或低功耗系统。
  • 良好的输入精度:Vos 5 mV、Ib 250 nA、Ios 50 nA,可实现稳定的门限判定。
  • 双路集成:两路比较器在单芯片内实现,节省 PCB 空间与成本。
  • SOP-8 封装:标准化封装,便于自动贴装与大规模生产。

(注:LM393 系列常见为开漏输出结构,在设计中需外接上拉电阻以生成逻辑电平输出。)

四、典型应用场景

  • 传感器信号检测与放大前的阈值比较(温度、光、压力等)
  • 电源管理:欠压/过压检测、充放电保护电路
  • 波形整形:方波、脉冲整形与零交叉检测
  • A/D 比较器参考、限幅与窗口比较器实现
  • 工业控制、家电、仪表及汽车电子(在对应温度等级内)

五、封装与订购信息

  • 品牌:GOODWORK(固得沃克)
  • 封装形式:SOP-8(表面贴装)
  • 订购时请确认工作温度等级(0 ℃~+70 ℃)、批号及供货稳定性,并按实际应用考虑是否需要额外的 ESD 与浪涌保护。

六、使用与设计注意事项

  • 输出为开漏/开集电极时必须使用适当的上拉电阻;上拉电压不得超过器件允许的电源范围。
  • 输入共模范围与电源关系密切,接近电源轨时性能可能下降,应在电路仿真或样片验证后再量产。
  • 在噪声环境下建议并联旁路电容并在电源脚附近布置去耦电容,以减少瞬态误触发。
  • 若系统对温漂和失调有更高要求,可考虑采用后续校准或选择精度更高的比较器型号。

如需原理接线示例、典型应用电路或更详细的电气特性曲线(推挽/漏极限、响应时间等),可提供具体应用场景,我将据此给出更精确的设计建议。

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
