LMV358MM/TR 产品概述

一、产品简介

LMV358MM/TR 是华冠(HGSEMI)推出的双路低压差、轨到轨输入/输出运算放大器,封装为 MSOP-8。器件为内部补偿型放大器,适用于电池供电与低电压系统,提供良好的直流精度与低功耗特性。

二、主要特点

  • 双通道运算放大器,封装:MSOP-8。
  • 轨到轨输入与轨到轨输出,便于更宽输入/输出动态范围。
  • 单电源工作电压:2.1V ~ 5.5V;最大电源差(Vdd–Vss)7.5V;亦支持对称分裂电源(等效 ±1.25V ~ ±2.75V)。
  • 内部补偿,稳定性好,易于单增益配置。
  • 静态电流(Iq):约 45 µA(低功耗)。
  • 输出驱动能力:约 18 mA。

三、电气性能要点

  • 增益带宽积(GBW):约 1 MHz,适合中低频率放大与滤波应用。
  • 输入失调电压(Vos):约 3.5 mV,温漂(Vos TC):约 2.7 µV/℃,适合对直流精度有要求的场合。
  • 输入偏置电流(Ib):约 1 pA,输入失调电流(Ios):约 10 pA,利于高阻抗传感器接口。
  • 压摆率(SR):600 V/ms,可满足较快边沿的信号调理需求。
  • 输入电压噪声密度:约 27 nV/√Hz @1 kHz,信噪比良好。
  • 共模抑制比(CMRR):约 88 dB,保证共模干扰抑制能力。

四、典型应用

  • 便携仪器与电池供电设备的信号放大与滤波。
  • 传感器前端(温度、电流、电压传感)——高输入阻抗有利于微弱信号采集。
  • 数据采集前置放大、比较器驱动与低频抗混叠滤波器。
  • 工业控制与便携医疗设备等需低功耗、轨到轨输入/输出的场合。

五、封装与订购信息

  • 封装形式:MSOP-8,适合空间受限的表面贴装设计。
  • 型号示例:LMV358MM/TR(华冠 HGSEMI),具体订购请参考供应商或代理商提供的包装与最低订购量信息。

六、布局与使用建议

  • 电源端做好去耦:在 Vcc 和 Vss 旁并联 0.1 µF 陶瓷电容以抑制高频噪声。
  • 由于输入偏置电流与失调电流极小,对高阻抗节点建议使用防护与短走线,必要时加隔离电阻或缓冲。
  • 输出驱动接近 18 mA,避免长时间驱动大容性负载以免出现振荡或过热,必要时加输出缓冲或阻尼电阻。
  • 布局时把敏感模拟走线远离数字开关干扰源,接地采用单点或局部良好回流设计。

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
