LM2904XS8G/TR 产品概述

一、产品简介

LM2904XS8G/TR 是圣邦微(SGMICRO)推出的一款双运算放大器,封装为 SOIC-8,面向工业级应用。器件具备高共模抑制比(CMRR = 118 dB)、较低噪声密度(eN = 36 nV/√Hz @1 kHz)和宽工作温度范围(-40℃ 至 +125℃),适合精密差分测量与低噪信号放大场合。

二、主要参数

  • 放大器数:双路
  • 共模抑制比:118 dB
  • 输入噪声密度:36 nV/√Hz @1 kHz
  • 增益带宽积(GBP):1.1 MHz
  • 压摆率(SR):350 V/ms
  • 输入失调电压(Vos):5.8 mV
  • 输入偏置/失调电流(Ib / Ios):10 pA / 10 pA
  • 静态电流(Iq):440 μA
  • 输出电流:18 mA
  • 电源范围:单电源 3 V ~ 32 V;双电源 VEE~VCC:±1.5 V~±16 V(等效表示)
  • 最大电源差:32 V
  • 工作温度:-40℃ ~ +125℃

三、典型应用

  • 精密传感器前端放大(差分测量、桥式传感器)
  • 低噪声信号拾取与处理(前置放大器)
  • 工业控制与数据采集系统
  • 便携式与汽车电子(满足宽温度与宽电源要求)

四、封装与可靠性

SOIC-8 封装利于标准 PCB 组装与散热,适配批量生产与自动化贴装。器件在宽温范围和较高电源容差下仍保持稳定性能,适合工业级长期可靠性设计。

五、设计建议

  • 在低噪声应用中配合良好布局和旁路电容以降低电源噪声影响。
  • 考虑 Vos(5.8 mV)与偏置电流对高阻抗传感器的影响,必要时进行偏置补偿或采用差分拓扑。
  • 输出负载接近 18 mA 时需注意功耗与热管理。
  • 对带宽与相位裕度要求较高的系统,应留意 GBP(1.1 MHz)与压摆率对大信号响应的限制。

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
