LM293DR 是由德州仪器(Texas Instruments)研发的一款高性能差分比较器,具有两路输入通道,支持开漏输出,以适应各种应用需求。该比较器的设计旨在提供优秀的电压比较性能,特别是在低电压和低电流环境下的应用,广泛应用于传感器信号处理、电压监控及其他自动化系统中。
这一宽广的电源电压范围使得 LM293DR 可以在多种电源条件下正常工作,提升了整个系统的适应性。
输入补偿电压:最大输入补偿电压为 5mV,即使在30V的工作条件下,LM293DR 依然可以保持高准确性。这一特性对于要求高精度电压比较的应用尤为重要。
输入偏置电流:其最大输入偏置电流为 0.25µA(在5V供电下),极低的输入电流非常适合与高阻抗传感器的接口,确保信号的完整性而不会被拉低。
输出电流:LM293DR 的典型输出电流为 20mA,能够驱动相对较大的负载,满足一般的控制和指示需求。
静态电流:器件的最大静态电流为 2.5mA,低静态功耗设计十分适合那些对功耗有严格要求的便携设备。
LM293DR 的工作温度范围为 -25°C 至 85°C,能够在恶劣的环境条件下保持可靠的性能。这一特性使得该器件适用于汽车、工业控制、网络设备及各种户外应用。
LM293DR 采用 8-SOIC 封装,尺寸为 0.154 英寸(3.90mm 宽),属于表面贴装型(SMD),便于在现代电子设备的高密度布线中进行使用。该封装形式不仅减小了电路板面积,同时也提高了生产效率。
由于其优异的性能和灵活的配置,LM293DR 被广泛应用于多个领域,包括但不限于:
LM293DR 是一款具有丰富功能和良好性能的差分比较器,既可以满足高精度的电压比较需求,又具备低功耗和宽电源电压范围的优势,适合于多种应用场景。在选择合适的比较器时,LM293DR 凭借其特有的特性与出色的性能,成为电子设计工程师的理想选择。通过德州仪器提供的高可靠性和丰富的应用支持,LM293DR 无疑将为各种电子应用提供强大的支持和保障。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
