NJM8068G-TE2 产品概述

一、概述

NJM8068G-TE2 是 NISSHINBO 推出的高性能双声道音频放大器,定位于低噪声、超低失真的小信号音频前级/驱动应用。器件集成度高、静态功耗低,适用于对音质和信噪比有严格要求的便携及固定式音频系统。

二、主要性能参数

  • 声道数:双声道(Dual)
  • 工作电压:支持单电源 4V~18V,亦可在对称双电源(±4V~±18V)下工作;对需负轨的系统亦兼容
  • 总谐波失真 + 噪声(THD+N):0.001%(典型)
  • 信噪比(SNR):约 120 dB(低噪声设计)
  • 静态电流(Iq):约 5 mA(器件整个工作电流,低功耗利于便携)
  • 工作温度:-40℃ ~ +125℃
  • 封装:SOP-8

三、特点与优势

  • 极低失真与极高信噪比,能有效还原细节,适合高保真音频链路;
  • 低静态电流与宽电源范围,便于电池供电与车载等不同场景使用;
  • 宽温度范围与工业级可靠性,适合严苛环境;
  • SOP-8 标准封装,便于批量 PCB 布局与回流焊接。

四、典型应用场景

  • 高保真便携式音频播放器与随身 DAC 放大段;
  • 桌面音响、主动音箱前置放大器或驱动级;
  • 汽车音响前级、低噪声麦克风预放、专业音频设备;
  • 任何对 THD+N 与 SNR 有高要求的模拟前端。

五、典型电路与设计要点

  • 对于单电源应用,输入端建议采用直流隔离电容并在输入端设置合适的偏置网络;双电源配置可省去耦合电容,简化设计;
  • 电源去耦十分关键:建议在供电端近芯片处并联 0.1 μF 与 10 μF 电容以抑制高频与低频纹波;
  • 输出端若驱动容性负载或长线,应考虑串联小阻(如 0.1–1 Ω)或 RC 阻尼网络以避免振荡;
  • PCB 布局时将模拟地与电源 decoupling 归流路径做短而粗,输入与输出信号线分离,避免环路面积过大。

六、封装与可靠性

SOP-8 封装利于自动化生产与散热,使用时应遵循回流焊温度曲线,避免反复热循环。器件工作温度覆盖 -40℃ 至 +125℃,适合工业级应用。

七、选型与使用建议

在对噪声与失真极端敏感的系统中,NJM8068G-TE2 提供了良好的性价比与兼容性。设计时建议评估系统增益配置、负载阻抗与电源品质,配合良好 PCB 及电源滤波设计以发挥器件的最佳性能。出货前通过带通滤波器和实际负载下的 THD+N、频响与稳定性测试,确认系统满足目标指标。

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
