4051G-S16-R 产品概述

一、产品简介

4051G-S16-R 是 UTC(友顺)推出的一款单片 8:1 模拟多路开关/多路复用器,封装为 SOIC-16。器件支持宽电源电压范围(3V 至 18V),在工业级温度范围内可靠工作(-40℃~+125℃),具有低导通电阻、较小导通电容以及适合中频应用的带宽与传播延迟,适用于多通道信号选择、传感器前端切换、音频/视频路由及数据采集等场景。

二、主要性能参数

  • 开关电路:8:1 多路复用/解复用(Y0~Y7 与公共端 Z 之间双向切换)
  • 工作电压:3V ~ 18V(单电源或对称电源工作)
  • 导通电阻(Ron):典型 250Ω(受电源电压、温度和输入电压影响)
  • 导通电容(Con):10pF(典型)
  • 带宽:约 17MHz(-3dB 点)
  • 传播延迟(tpd):约 35ns
  • 工作温度:-40℃ ~ +125℃
  • 封装:SOIC-16
  • 品牌:UTC(友顺)
    这些参数决定了器件在中低频模拟信号切换时有良好表现,但对高频、高精度模拟路径需考虑 Ron 与 Con 的影响。

三、功能与典型引脚说明

器件通常包含三个地址选择脚(S0、S1、S2),一个使能/禁止脚(INH 或 EN),以及八路通道 Y0Y7 与公共端 Z。通过 S0S2 组合选择对应的通道,EN 控制器件导通或断开。器件为双向模拟开关,支持正负信号(依电源摆幅而定)。

四、应用场景

  • 多路传感器数据采集:单片 MCU 选择多个模拟传感器输入,节省 ADC 通道。
  • 音频通道切换:音频源切换、效果器路由(在 17MHz 带宽范围内适合音频应用)。
  • 仪器仪表与测试设备:低频信号路由、信号采样前端切换。
  • 电池供电和便携设备:宽电压范围利于不同供电方案。

五、设计与使用建议

  • 电源去耦:靠近 VCC 和 GND 放置 0.1µF 陶瓷电容,抑制开关瞬态噪声。
  • 考虑 Ron 的影响:250Ω 的导通电阻在低阻负载上会引入电压降或影响带宽,适合与缓冲放大器或高输入阻抗 ADC 配合使用。
  • 高频注意:10pF 的通导电容与线路负载形成低通,若需更高带宽应选高速开关芯片。
  • 控制引脚电平:确保逻辑驱动电平与器件供电匹配;在未使用时将 EN 置为禁用状态以避免浮空。
  • 布局建议:模拟地与数字地分割,信号走线尽量短且避免与高速数字线平行,减小串扰。

六、比较与选型提示

4051G-S16-R 在价格与功能上适合对通道数与成本有平衡需求的应用;若对导通阻抗或带宽有更严格要求,可考虑低 Ron 或高速开关系列。对于严格精密测量场合,应评估开关的非线性与温漂对系统精度的影响。

总结:4051G-S16-R 是一款可靠的 8 路模拟开关解决方案,凭借宽电源范围和工业级温度能力,适合多种通道切换需求。在实际设计中注意导通电阻与导通电容带来的影响,并做好电源与地的布局与去耦,即可发挥其稳定的通道切换能力。

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
