AD8671ARZ-REEL 产品概述
一、概述
AD8671ARZ-REEL 是来自 ADI/Linear 的高精度单路运算放大器，封装为 SOIC-8，卷装出厂，适合批量贴片生产。器件针对低噪声、低失调和高共模抑制场合优化，内部补偿、ESD 保护与输入保护使其在精密信号链中易于使用并具备良好的鲁棒性。
二、关键规格（典型/最大）
- 放大器数：单路
- 电源电压范围：-15V ~ +15V（双电源）
- 输入失调电压 Vos：20 μV
- 输入失调电压温漂 Vos TC：300 nV/℃
- 增益带宽积 GBW：10 MHz
- 压摆率 SR：4 V/μs
- 共模抑制比 CMRR：120 dB
- 输入电压噪声密度 eN：2.8 nV/√Hz @1 kHz
- 输入偏置电流 Ib：3 nA，输入失调电流 Ios：6 nA
- 静态电流 Iq：3 mA
- 输出电流能力：20 mA
- 工作温度范围：-40℃ ~ +125℃
三、功能与保护
- 内部补偿：保证在单位增益条件下稳定，方便构建缓冲及低增益放大器。
- ESD 保护：提高制造与现场使用可靠性。
- 反相输入保护：降低在输入超出规格或单端输入情况下发生相位反转的风险，保护前端器件与系统稳定性。
四、应用场景
适用于对噪声与偏置要求较高的场合，例如：
- 精密差分/单端信号放大（传感器信号调理）
- 仪表放大器前端、桥式传感器驱动与测量
- 低噪声前置放大器、音频前端与高精度数据采集通道
- 主动滤波器与精密比较电路（需要注意速度与压摆率匹配）
五、设计注意事项与建议
- 电源去耦：在放大器电源引脚附近并联 0.1 μF 与 10 μF 去耦电容，减小高频噪声与振铃。
- 布局：输入与反馈环路尽量缩短，阻抗控制良好以发挥低噪声特性。
- 输入保护：若可能出现大信号注入或电容负载，建议在输入端串入小电阻或使用限流保护元件。
- 输出驱动：20 mA 输出能力适合驱动中等负载，若驱动大电流或重电容负载需加缓冲或限制环路带宽。
六、封装与订购信息
- 型号：AD8671ARZ-REEL
- 品牌：ADI / Linear
- 封装：SOIC-8，卷带盘装（REEL），适合 SMT 自动化生产。
- 建议在量产时通过正规渠道索取封装图与完整器件手册以确认引脚排列与安装注意事项。
总结：AD8671ARZ-REEL 集低失调、低噪声与高 CMRR 于一体，适合用于高精度信号调理场合。其内部补偿与保护特性降低了系统设计复杂度，是精密仪表与传感器前端的优选器件。

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.
