MC34074G-S14-R 产品概述

一、产品简介

MC34074G-S14-R(UTC 友顺)为四路精密通用运算放大器,适用于单电源与双电源系统。器件在宽电源范围内工作(单电源3V~44V,最大电源差44V),每通道静态电流低、带宽适中,适配传感器接口、缓冲放大与通用信号处理应用。

二、主要规格

  • 放大器数:四路(Quad)
  • 输入失调电压 Vos:典型可达到≈500μV(视批次调校),上限3mV;温漂 Vos TC:10μV/℃
  • 输入偏置电流 Ib:700nA;输入失调电流 Ios:50nA
  • 共模抑制比 CMRR:97dB
  • 噪声密度 eN:32nV/√Hz @1kHz
  • 增益带宽积 GBP:4.5MHz;压摆率 SR:13V/μs
  • 静态电流 Iq:约2.5mA(器件典型);输出驱动能力:最大30mA
  • 工作温度范围:-20℃ ~ +85℃
  • 封装:SOP-14
  • 品牌:UTC(友顺)

三、性能特点

  • 宽工作电压范围,适用于汽车电子低压系统及工业电源场景。
  • 低噪声(32nV/√Hz)与较高的共模抑制比(97dB),有利于差分微弱信号放大与高精度测量前端。
  • 中等增益带宽(4.5MHz)与较快压摆率(13V/μs),能满足多级滤波和中速信号处理需求。
  • 每通道可提供较大输出电流(30mA),适合驱动一般模拟负载或下一级器件。

四、典型应用

  • 传感器前端信号调理(压力、温度、应变计等)
  • ADC/DAC 缓冲与驱动
  • 有源滤波器与音频前置放大(中低频段)
  • 通用比较与电平检测(非高速)

五、封装与环境适用性

SOP-14 封装便于批量贴装与散热管理。器件工作温度覆盖常见工业级范围(-20℃~+85℃),在高温或苛刻环境时建议参考完整可靠性与热阻参数,并做热设计预留。

六、使用建议与PCB布局

  • 电源引脚近距离放置去耦电容:建议0.1μF陶瓷并联10μF电解/钽电容,靠近Vcc与GND引脚焊盘。
  • 输入与反馈回路走线尽量短,避免和高频开关或大电流回路并行,减少共模干扰。
  • 设计低阻抗接地平面以降低噪声。
  • 若用于精密测量,先行评估失调及温漂,并考虑外部偏置或后期校准。
  • 避免长期在极限输出电流与高温同时工况下工作,以免加速老化。

总结:MC34074G-S14-R 是一款面向通用精密放大与信号调理的四路运放,兼顾低噪声、高CMRR和宽电源范围,适用于多数工业与消费类模拟前端场合。在具体设计中请参照器件完整数据手册确定输入/输出共模范围、功耗与热限。

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
