NJM5532D 产品概述

一、产品简介

NJM5532D 是 NISSHINBO 推出的双路运算放大器,面向对低噪声、高线性及较高驱动能力有要求的音频和通用放大应用。器件采用 8 引脚 DIP 封装,集成两路放大单元,便于在双声道音频、前置放大和滤波器等电路中使用。

二、主要特性

  • 双路运算放大器设计,便于 stereo 或差分通道布局。
  • 增益带宽积 (GBP): 10 MHz,适合中低频放大与滤波应用。
  • 压摆率 (SR): 8 V/μs,可处理中等速度的信号边缘。
  • 低噪声:噪声密度 5 nV/√Hz @1 kHz,适合音频前端。
  • 低输入失调电压:Vos = 500 μV,减少直流校准工作量。
  • 较小输入偏置/失调电流:Ib = 200 nA,Ios = 10 nA,利于高阻抗源驱动。
  • 共模抑制比 (CMRR):100 dB,保证差模信号放大准确性。
  • 输出短路或驱动能力:输出电流可达 38 mA。
  • 静态电流 (Iq):9 mA/对(典型),适中功耗。
  • 工作温度范围:-20℃ ~ +75℃。
  • 支持最大总电源电压 44 V;常见供电配置可为对称 ±(最高约22 V)或单电源模式(典型单端 3 V 至 22 V)。
  • 封装:8-DIP,便于面包板与穿孔板装配与调试。

三、典型电气参数(概要)

  • Vos: 500 μV
  • Ib: 200 nA;Ios: 10 nA
  • GBP: 10 MHz;SR: 8 V/μs
  • eN: 5 nV/√Hz @1 kHz
  • CMRR: 100 dB
  • Iq: 9 mA;输出电流: 38 mA

四、典型应用

  • 专业/家用音频前置放大器与均衡器
  • 低噪声麦克风前置放大与混音台输入缓冲
  • 主动滤波器、音频缓冲与驱动中低阻抗负载
  • 通用信号放大与差分放大场合

五、封装与引脚建议

NJM5532D 提供标准 8 引脚 DIP 封装,利于手工焊接和原型验证。常见布局应注意电源去耦(每个放大单元靠近电源引脚放置 0.1 μF 与 10 μF 旁路电容),并为输入端提供防射频干扰的滤波/阻抗匹配网络以发挥低噪声优势。

六、使用与可靠性建议

  • 在高增益或高频应用中注意闭环裕度与补偿,避免振荡;
  • 驱动较低阻抗负载时监测器件发热,必要时考虑散热或降低静态功耗;
  • 工作温度边界应保持在 -20℃ 至 +75℃ 范围内以保证参数稳定;
  • 供电极性与幅值应严格遵守器件额定,以免超过最大电源宽度 44 V。

NJM5532D 以其低噪声、良好驱动能力和通用性,适合要求高保真和稳定性的音频与信号处理电路。若需详细管脚图与典型电路,请参阅厂商数据手册。

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
