SSM2167-1RMZ-REEL 单声道AB类音频功率放大器产品概述

一、产品核心定位与应用场景

SSM2167-1RMZ-REEL是亚德诺半导体(ADI)推出的单声道AB类音频功率放大器,专为低电压、便携化、对音频失真要求较高的场景设计。其核心价值是在紧凑封装内平衡“音频保真”与“电源效率”,适配电池供电的移动设备、工业手持终端及车载辅助音频系统,解决小型化设备中“小体积”与“音频质量”的矛盾。

二、关键性能参数深度解析

该器件的参数围绕“便携适配”与“音频保真”优化,核心指标如下:

1. 音频保真与抗干扰

  • 总谐波失真+噪声(THD+N):0.2%:典型工作条件下失真度极低,可还原清晰音频,避免“毛刺感”“浑浊感”,满足入门至中端音频设备需求;
  • 电源纹波抑制比(PSRR):45dB:有效抑制电源纹波(如电池充放电、开关电源噪声),确保音频纯净,适配锂电池或低成本开关电源系统。

2. 电源与功耗优化

  • 宽电压范围:2.5V~5.5V:兼容2节AA干电池(3V)、单节锂电池(3.7V)及5V USB供电,无需额外升压/降压电路;
  • 低静态电流(Iq):5mA:待机功耗极低,延长电池续航,适合条码扫描器、智能手环等手持设备。

3. 环境与可靠性

  • 宽温工作:-40℃~+85℃:符合工业级标准,可在极端环境(低温户外、高温车载舱内)稳定工作;
  • 单声道配置:简化系统设计,适合单扬声器输出(提示音、单声道语音),降低BOM成本与布线复杂度。

三、封装与可靠性设计

采用10-MSOP封装,具备以下优势:

  • 超小体积:尺寸约3mm×3mm,比传统DIP封装缩小70%以上,适配智能手表、蓝牙耳机等小型化设备;
  • 高可靠性:经ADI抗冲击、振动测试,符合MIL-STD-883标准,应对移动设备跌落、振动场景;
  • 散热优化:内部热阻路径设计可支持短时间大负载输出(典型4Ω负载下约100mW,需结合实际验证)。

四、典型应用方案

该器件覆盖多领域典型场景:

  1. 便携式音频:MP3播放器、单声道蓝牙耳机、智能手环语音提示;
  2. 车载辅助:仪表盘故障提示、倒车雷达语音播报、车载蓝牙单声道输出;
  3. 工业手持:条码扫描器操作提示、数据采集器语音反馈;
  4. 智能家居入门:小型单声道智能音箱、智能门锁语音提示。

五、选型与使用注意事项

确保性能稳定需注意:

  1. 电源匹配:避免超5.5V(损坏器件)或低于2.5V(失真升高);
  2. 负载阻抗:建议匹配4Ω~8Ω扬声器,避免低阻抗导致过热;
  3. 散热管理:长时间大负载时,PCB增加散热铜箔,远离高温区域;
  4. 布线规范:音频线尽量短,远离电源走线,输入串100Ω~1kΩ电阻降噪声;
  5. 静电防护:MSOP对ESD敏感,焊接用接地烙铁,避免人体静电损坏。

总结

SSM2167-1RMZ-REEL是高性价比单声道AB类功放,以紧凑封装、宽电压、低失真与低功耗为核心优势,适配便携、工业、车载等多场景。ADI的品牌可靠性与成熟设计,降低系统开发风险,是小型化音频系统的理想选择。

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
