RC4580M/TR 产品概述

一、器件概况

RC4580M/TR 是华冠(HGSEMI)推出的一款双运算放大器,专为音频信号处理与音色控制电路优化设计。器件在低噪声、高增益带宽和低失真方面表现优异,适用于前置放大、主动滤波、有源均衡器以及需较大输出驱动的耳机放大场合。封装为 SOP-8,适配常见通用线路板与小批量装配需求。

二、关键电气参数

  • 放大器数:2(双运放)
  • 最大电源宽度 (Vdd−Vss):32 V(双电源 ±16 V)
  • 增益带宽积 (GBW):15 MHz
  • 输入失调电压 (Vos):3 mV
  • 压摆率 (SR):5 V/µs
  • 输入偏置电流 (Ib):500 nA
  • 输入失调电流 (Ios):5 nA
  • 共模抑制比 (CMRR):110 dB
  • 静态电流 (Iq):6 mA(典型)
  • 工作温度范围:−40 ℃ ~ +85 ℃
  • 封装:SOP-8

三、主要性能特点

  • 低噪声、高增益带宽,保证音频带宽内良好的频率响应与信噪比。
  • 低失真与良好的共模抑制,适合高保真音频路径与精密测量前端。
  • 较高输出驱动能力,可在较大负载下维持稳定输出,适用于耳机与低阻抗驱动。
  • 宽电源电压范围(最高 32 V)与工业级温度范围,适配多种供电与应用环境。

四、典型应用场景

  • 音频前置放大与话筒预放大器
  • 有源低/高通滤波器、主动等化器(音调控制)
  • 耳机放大器与便携音响输出级(在合理偏置与散热下)
  • 工业测量放大器与信号调理电路

五、使用与设计建议

  • 电源去耦:在每个电源引脚附近并联 0.1 μF 陶瓷与 10 μF 电解电容,抑制高频与低频干扰。
  • 输入与输出布局:输入引脚走线尽量短,使用星形接地或单点接地以降低地回路噪声。
  • 增益与带宽:基于 15 MHz GBW,建议闭环增益不要过高以保持所需带宽与相位裕度;对于高增益应用可考虑补偿或选择合适环路滤波。
  • 负载与稳定性:避免直接驱动强容性负载,必要时在输出与负载之间串入小阻抗(10–100 Ω)或并联阻尼网络以保证稳定性。
  • 热设计:静态电流 6 mA/运放,在双运放持续大电流输出场景应关注封装散热与环境温度。

六、封装与引脚说明

  • 封装:SOP-8(常见 8 引脚双运放封装),便于替换与批量生产。建议参考器件数据手册获取详细引脚排列与引脚功能。

七、可靠性与环境

  • 工作温度范围 −40 ℃ 到 +85 ℃,适合工业级与民用环境。
  • 建议在高温或高功耗负载下增加热管理措施,延长产品寿命并确保长期稳定工作。

RC4580M/TR 以其在音频领域的综合性能(低失真、较高带宽与良好驱动能力)为音频设备与精密信号处理提供了可靠选择。欲获得详细电气特性曲线、典型应用电路与封装尺寸,请参考华冠(HGSEMI)官方数据手册。

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
