LM4040DIM3X-2.5/NOPB 是由德州仪器 (TI) 制造的一款高精度、低噪声电压基准芯片。该器件以其卓越的性能和紧凑的封装设计,广泛应用于各种需要稳定和准确电压参考的电子系统。
LM4040DIM3X-2.5/NOPB 提供了极高的输出电压精度,仅有 ±1% 的容差,这使得它特别适合于要求严格的应用场景,如数据转换器、测量仪表和高性能模拟电路。同时,其低噪声性能(35µVrms 在 10Hz 至 10kHz 范围内)确保了输出信号的清晰和稳定。
该器件的温度系数为 150ppm/°C,这意味着即使在广泛的温度范围下,输出电压也保持非常稳定。这对于那些需要在不同环境条件下保持准确性的应用尤为重要。
LM4040DIM3X-2.5/NOPB 可以提供高达 15mA 的输出电流,这使得它能够支持多个负载同时使用同一参考电压,提高了系统的整体效率和灵活性。
器件的阴极电流仅为 70µA,这意味着在正常操作条件下,它对系统的能耗影响非常小,非常适合于低功耗设计。
支持从 -40°C 到 85°C 的广泛工作温度范围,使得 LM4040DIM3X-2.5/NOPB 可以在各种极端环境中可靠运行。
采用 SOT-23-3 封装,这是一种非常紧凑且适合现代电子产品的小型封装。这种封装不仅节省了 PCB 空间,还简化了生产过程和维护工作。

电源选择: 选择合适的输入电源以确保稳定的操作条件。输入电源应能够提供足够的电流,并且具有良好的噪声特性。
LM4040DIM3X-2.5/NOPB 是一款功能强大、性能卓越的电压基准芯片,适用于各种需要高精度和稳定参考电压的应用场景。其紧凑的封装设计、低噪声性能和宽工作温度范围,使其成为现代电子系统设计中的重要组成部分。通过正确使用和布局,这款器件可以为您的系统提供长期可靠的服务。
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.
