AD780BRZ-REEL7 产品概述

一、产品简介

AD780BRZ-REEL7 是 ADI / Linear 提供的一款高精度低噪声电压基准芯片,SOIC-8 封装卷盘供货。器件支持 2.5V 或 3.0V 固定输出(可通过选型获得),输入工作电压宽范围 4V~36V,输出驱动能力可达 10mA,适合要求高稳定性与低漂移的精密测量和数据采集场合。

二、主要特性

  • 输出电压:2.5V / 3.0V(可选)
  • 输入电压范围:4V ~ 36V
  • 输出电流:最多 10mA(短路保护与热限制视具体应用)
  • 温度系数:典型 3 ppm/℃,适合长期稳定测量
  • 噪声(0.1Hz–10Hz):4 μV p-p(低频噪声优异)
  • 静态电流(Iq):约 1 mA,适合低功耗系统
  • 最小可调/负载电流:700 μA(保持规范工作及精度)
  • 支持串联(缓冲/有源)与并联(多器件并联提高能力或冗余)配置
  • 内置温度传感器,便于现场温度监测与补偿
  • 工作温度范围:-40℃ ~ +85℃
  • 封装:SOIC-8,型号为 AD780BRZ(REEL 卷盘包装便于批量贴片)

三、典型应用

  • 精密 ADC/DAC 的参考电压源
  • 精密电源与校准设备
  • 工业过程控制与传感器前端
  • 便携式测量仪器与数据记录器
  • 温度补偿与长期漂移监测系统(利用内置温度传感器)

四、设计与使用要点

  • 最小负载电流:为保证输出误差在规格范围内,系统应提供不少于 700 μA 的负载或并联负载网络。
  • 去耦与滤波:在输入与输出端放置低 ESR 去耦电容(靠近引脚)可抑制瞬态与射频干扰,降低噪声影响。
  • 布局建议:尽量缩短输出与接地回路,采用单点接地或良好平面地,避免参考引脚环路经过数字噪声区。
  • 温度传感器应用:内置温度传感器可用于实时温度校正,配合微控制器实现温漂补偿,提高系统长期稳定性。
  • 串/并联配置:当需要更高驱动能力或冗余时,可采用并联多只参考器件(注意配对与均流);串联配置适用于缓冲或形成更复杂参考网络时的级联使用。

五、选型与采购

AD780BRZ-REEL7 为工业级器件,适合批量 SMT 贴片生产(REEL 卷盘)。在选型时注意区分 2.5V 与 3.0V 输出版本及温度等级,依据系统电源范围与负载需求确认是否需要并联或外部缓冲放大器。

总结:AD780BRZ-REEL7 以其低噪声、低温漂和宽输入电压特性,适合对参考精度与长期稳定性要求较高的仪器仪表与工业控制场景。正确的去耦、布局与最小负载满足能确保其在实际系统中的最佳性能。

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
