BE8002D 产品概述

一、产品简介

BE8002D 是 BORN(伯恩半导体)推出的一款单声道 AB 类音频功率放大器,采用 SOP-8 封装,面向便携式及消费类音频终端。器件优化了声音失真与电源抑制性能,在低功耗条件下仍能提供良好的驱动能力,适合驱动单只中小阻抗扬声器。

二、关键参数

  • 工作温度:-40℃ ~ +85℃
  • 工作电压:2.2V ~ 5.5V
  • 静态电流(Iq):10mA
  • 功放类型:AB 类
  • 总谐波失真+噪声(THD+N):0.1%
  • 电源纹波抑制比(PSRR):85dB ~ 90dB(随频率与测试条件变化)
  • 扬声器通道数:单声道
  • 输出功率:2W × 1 @ 4Ω;3W × 1 @ 4Ω(受供电电压、负载与测量条件影响)
  • 封装:SOP-8

三、性能特点

  • 低静态电流:典型静态电流 10mA,有利于电池供电设备延长待机时间。
  • 低失真:THD+N 0.1% 意味着在额定输出下能够提供较高的音质保真度。
  • 优秀的电源抑制:PSRR 高达 85–90dB,可有效抑制电源纹波对音频输出的影响,提升低频噪声表现。
  • 宽工作电压范围:2.2V 至 5.5V,兼容多种单电源系统,适配不同电池或供电方案。
  • AB 类线性驱动:在保证较好音质的同时,在输出瞬态时具有相对较好的驱动力。

四、典型应用

  • 便携式蓝牙音箱、迷你音响
  • 平板、便携媒体播放器及便携电视
  • 玩具、数码相框等内置音频播放设备
  • 车载辅助音频(工作温度及电源条件满足时)
  • 任何需单通道、低失真音频放大且封装空间受限的场景

五、设计与使用建议

  • 电源去耦:为发挥高 PSRR 性能,建议在 VCC 近端使用低 ESR 电容进行去耦,并在电源输入处采用 0.1µF 与较大容量的并联组合。
  • 散热与负载:在高输出功率(如接近 3W/4Ω)工作时注意芯片功耗与封装散热,合理安排 PCB 铜面与散热过孔以降低结温。
  • 输出耦合与滤波:根据系统需要选择合适的输出耦合电容与滤波网络,避免低频下的直流偏移及扬声器受损。
  • 布局注意:模拟地与电源地的分离、输入信号线路短且远离开关噪声源,有利于保持低噪声性能。
  • 测试条件:规格中输出功率和 PSRR、THD+N 等指标受信号频率、供电电压及测量带宽影响,设计时请参考器件详细数据手册中的测试条件。

六、封装与环境适应性

BE8002D 提供 SOP-8 封装,便于 SMT 贴装与批量生产。器件工作温度范围覆盖工业级(-40℃ ~ +85℃),适应一般工业及消费电子环境。

总结:BE8002D 是一款面向中小功率音频应用的单声道 AB 类功放,兼顾低功耗、低失真与良好电源抑制,适合对音质、供电灵活性和封装尺寸有要求的产品设计。如需进一步电气特性曲线、引脚定义及典型应用电路,请参阅 BE8002D 详细数据手册或联系厂商技术支持。

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
