TL084CDR是德州仪器公司(Texas Instruments)生产的一款高性能FET输入运算放大器,专为许多高增益和高输入阻抗的应用而设计。它在电子工程师和设计师中广受欢迎,因其卓越的性能以及灵活的应用,广泛用于音频处理、信号调理、医疗设备以及其他高精度电子电路设计。
TL084CDR便于使用,支持多种电源配置,其额定供电电压范围为7V至36V (单极性) 或±3.5V至±18V (双极性)。这种灵活性使得TL084CDR能够适应多种电源条件,从而为设计师在不同的应用环境下提供了便利。
该运算放大器包含四个独立的放大器,其架构允许在同一封装内完成多个信号的处理。这在复杂的信号调理路径上尤为有用,能够有效节省电路板空间。
TL084CDR的压摆率为13V/μs,这个指标表明了其对快速变化信号的响应能力,能够处理高频信号并保持良好的线性度。此外,增益带宽积为3MHz,这意味着在增益较高的情况下,可以确保有效的操作频率,适用于需要较高精度的应用。
输入偏置电流为30pA,结合极低的输入补偿电压(3mV),确保了该运算放大器在高阻抗环境下的优异表现。由于输入偏置电流极低,TL084CDR非常适合用于高灵敏度的传感器信号放大或偏置电路,能够最小化对信号的干扰。
TL084CDR专为工业和商业环境设计,工作温度范围是0°C至70°C,保证了其在常规工作条件下的稳定性。这一特性使得TL084CDR适用于绝大多数电子设备的工作环境,为长期稳定性提供了保证。
该产品采用14-SOIC封装,尺寸为0.154英寸(约3.90mm宽),并实现表面贴装(fsurface-mount technology, SMT)。这种安装方式不仅使PCB设计更加紧凑,同时也加强了焊接的可靠性和降噪能力,适合自动化生产。
TL084CDR运算放大器的广泛应用包括但不限于:
综上所述,TL084CDR是一款功能强大、性能卓越的FET输入运算放大器,具有优异的输入特性和良好的工作稳定性,适用于多种电子应用。这款产品的多路输出、高效率和灵活的供电范畴,使得它成为了电子设计师的一个理想选择,无论是在音频处理、信号调理还是医疗设备领域,它都能展现出不凡的实力。随着技术的不断进步,TL084CDR的多种优势将使其继续在各种应用中占据重要地位。
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.
