LMV358IDR-MS 产品概述

一、产品简介

LMV358IDR-MS 是美森科(MSKSEMI)推出的一款双路低功耗运算放大器,封装为 SOP-8。器件支持轨到轨输入与轨到轨输出,在单电源或双电源工作条件下均能稳定工作,适合便携设备和工业测量等多种场合的模拟前端设计。

二、主要特性

  • 双路放大器,节省 PCB 面积与成本。
  • 最大电源宽度 (Vdd–Vss):5.5V;单电源工作电压范围 2.1V ~ 5.5V,双电源范围 Vee~Vcc = -2.75V ~ 2.75V。
  • 轨到轨输入与输出,便于在低电压和接近电源轨的信号条件下使用。
  • 增益带宽积(GBP):1.5MHz,适合低频到中频放大与滤波。
  • 压摆率(SR):1.2V/μs,满足大多数慢速信号的动态响应需求。
  • 极低输入偏置电流 Ib ≈ 2pA,输入失调电流 Ios ≈ 1pA,利于高阻抗传感器接口。
  • 输入失调电压 Vos ≈ 2mV,温漂 Vos TC ≈ 650nV/℃,在宽温度范围内保持良好精度。
  • 共模抑制比(CMRR):95dB,静态电流 Iq:约 50μA/通道(典型),适合低功耗系统。

三、电气性能概览

LMV358IDR-MS 在 2.1V 单电源条件下即可正常放大常见传感器和差分信号,轨到轨特性允许输入与输出接近电源轨,减少与电源相关的接口电路。GBP 1.5MHz 与 SR 1.2V/μs 表明该器件更适合直流放大、低通滤波与缓冲等应用,而非高带宽高速运放场合。超低输入偏置电流和良好的失调电压温漂使其在温度变化较大的环境中仍能保持稳定测量。

四、典型应用

  • 电池供电的便携测量仪器与数据采集前端
  • 传感器接口(高阻抗传感器如压力、电化学等)
  • 低频主动滤波与信号缓冲
  • 工业控制和过程测量中的模拟信号调理

五、优势与使用注意

优势在于低功耗、轨到轨能力与极低输入偏置电流,适合对功耗与输入偏置要求严格的系统。使用时需注意其带宽和压摆率限制:对于要求高开环增益或快速脉冲响应的场合,应评估 GBP 与 SR 是否满足需求;在高频环境下需采取良好布局与旁路电容以保证稳定性。

六、封装与环境

LMV358IDR-MS 提供 SOP-8 封装,适合常规贴片生产与焊接工艺。工作温度范围为 -55℃ 至 +125℃,可满足宽温区工业级应用需求。

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
