OPA333AIM5/TR 产品概述

一、产品简介

HGSEMI(华冠)OPA333AIM5/TR 是一款低成本、单通道的零漂(Zero-Drift)运算放大器,单位增益稳定并具备输入/输出轨到轨特性。器件采用专有自动校准技术,保证极低的输入失调电压与极小的温度漂移,同时消除意外的输出相位反转,适合要求长期稳定性的精密测量电路。

二、主要规格(典型值)

  • 单电源电压:1.8V ~ 5.5V
  • 双电源工作(±):±0.9V ~ ±2.75V
  • 输入失调电压 Vos:2 μV
  • 失调电压温漂 Vos TC:20 nV/℃
  • 增益带宽积 GBW:350 kHz
  • 压摆率 SR:0.16 V/μs
  • 共模抑制比 CMRR:115 dB
  • 输入电压噪声密度 eN:55 nV/√Hz @1 kHz
  • 输入偏置电流 Ib:70 pA;输入失调电流 Ios:140 pA
  • 静态电流 Iq:17 μA;输出驱动电流:5 mA
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOT-23-5

三、性能亮点

  • 极低失调与漂移:2 μV 的初始失调与 20 nV/℃ 的漂移,适合微伏级精密信号放大。
  • 轨到轨输入/输出:输入输出接近电源轨,扩大了输入共模范围和输出摆幅,利于低电压供电系统。
  • 零漂自动校准:内部补偿与自动稳零实现长期稳定性,减少外部调校要求。
  • 抗干扰与保护:内建 EMI/RF 抑制、ESD 保护与反相位输入保护,提高系统可靠性。
  • 低功耗:17 μA 静态电流适合电池供电与便携式应用;输出驱动 5 mA 满足传感器缓冲需求。

四、典型应用场景

  • 精密传感器信号调理(温度、压力、应变计等)
  • 便携式医疗与检测仪器的前端放大器
  • 电池供电的数据采集与低速滤波器
  • 工业控制中对低频微小信号的放大和缓冲

五、设计与使用建议

  • 为保证稳定与抗干扰,建议在电源引脚靠近封装处并联低 ESR 去耦电容(如 0.1 μF);若环境有强 RF 干扰,可加入额外滤波网络。
  • 由于压摆率和 GBW 属于低速规格,不适用于高速或大带宽驱动场合;更适合直流与低频精密信号处理。
  • 输出驱动能力有限,驱动大电容负载或低阻抗负载时需加缓冲或功率放大级。
  • 使用轨到轨输入时仍需关注共模下的精度和噪声表现,在接近电源轨的工作点做必要验证。

六、封装与供货

SOT-23-5 小尺寸封装,便于空间受限的便携或嵌入式系统设计。适合批量采购与替换常见精密放大器封装。若需样片或批量信息,请联系华冠(HGSEMI)或授权分销渠道获取更详细的器件型号与应用资料。

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
