QCPL-7847-500E 产品概述

一、概述

QCPL-7847-500E 为 Broadcom(博通)出品的单路放大器,专为 5V 单电源系统优化设计。器件工作电源范围为 4.5V 至 5.5V,最大电源差(Vdd‑Vss)可达 5.5V,适合微控制器和数字接口常见的供电环境。采用通用的 DIP‑8‑300mil 封装,便于面包板实验与快速原型验证。

二、主要性能参数

  • 放大器数:单路
  • 增益带宽积 (GBP):100 kHz
  • 输入失调电压 (Vos):300 μV;温漂 (Vos TC):3 μV/℃
  • 输入偏置电流 (Ib):500 nA;输入失调电流 (Ios):500 nA;Ios 温漂:450 pA/℃
  • 共模抑制比 (CMRR):76.1 dB
  • 输出电流:18.6 mA(典型);工作温度范围:-40℃ ~ +85℃
  • 单电源工作范围:4.5V ~ 5.5V
  • 封装:DIP‑8‑300mil;品牌:Broadcom

三、优势与特性

  • 低失调与低温漂:300 μV 的低输入失调及 3 μV/℃ 的温漂,有利于直流精度要求较高的传感放大和电压基准缓冲。
  • 合理的带宽与稳定性:100 kHz 的 GBP 适合滤波、缓冲、仪表前端和低速信号调理场合,利于系统设计中的频率裕量。
  • 适配 5V 单电源系统:工作电压范围与常见的逻辑电平兼容,便于与微控制器直接接口。
  • 工业级温度范围与通用封装:-40℃ 至 +85℃ 满足多数工业应用,DIP‑8 有利于开发调试与维修。

四、应用建议

  • 传感器接口:用于放大热电偶、电阻式传感器或电桥输出,配合合适的滤波与偏置电路可获得良好直流精度。
  • 数据采集前端:作为缓冲放大器或简单差分放大器以驱动 ADC 输入。
  • 信号调理与低频滤波:适合 1 kHz 以下或低中频带宽的滤波器、PI 控制器及模拟计算电路。
  • 教学与原型:DIP 封装便于面包板调试和实验室验证。

五、设计与使用注意事项

  • 电源旁路:在 Vdd 和 Vss 近端各放置 0.1 μF 陶瓷电容与 10 μF 旁路电容以抑制电源噪声并防止振荡。
  • 输入保护:若用于传感器系统,建议在输入端加短路保护与限流措施,以防输入瞬态或共模超范围带来的损坏。
  • 偏置与漂移考虑:对于高精度直流测量,可采用外部失调校准或差分架构以抵消失调与温漂影响。
  • 输出负载:器件输出驱动能力约 18.6 mA,驱动大电容或低阻负载时需关注稳定性与失真。

六、封装与可获得性

QCPL‑7847‑500E 提供常用的 DIP‑8‑300mil 封装,便于手工焊接与原型验证。建议向 Broadcom 授权分销商咨询最新交货期与批量采购信息。

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
