OP07M/TR — 精密低噪声运算放大器(HGSEMI 华冠)

一、产品概述

OP07M/TR 是华冠(HGSEMI)推出的一款单路精密运算放大器,针对高精度直流和低频信号放大设计。该器件具有极低的输入失调电压(150 μV)、高共模抑制比(CMRR 120 dB)与低噪声(10 nV/√Hz @1 kHz),适合精密测量、传感器信号调理与仪表级放大电路使用。封装为 SOP-8,TR 表示卷带(Tape & Reel)封装,方便 SMT 贴片生产线自动化装配。

二、主要性能参数(摘要)

  • 共模抑制比(CMRR):120 dB
  • 输入电压噪声密度(eN):10 nV/√Hz @1 kHz
  • 最大电源电压差(Vdd–Vss):44 V
  • 输入失调电压(Vos):150 μV
  • 放大器数量:单路
  • 输入偏置电流(Ib):1.8 nA
  • 增益带宽积(GBP):500 kHz
  • 工作温度范围:0 ℃ ~ +105 ℃
  • 输入失调电流温漂(Ios TC):15 pA/℃
  • 压摆率(SR):170 V/ms(即 0.17 V/μs)
  • 静态电流(Iq):2.7 mA
  • 允许电源范围(VEE ~ VCC):-3 V ~ +22 V
  • 输入失调电流(Ios):7 nA
  • 输入失调电压温漂(Vos TC):1.8 μV/℃

三、典型应用场景

  • 精密直流放大器与差分放大器
  • 传感器信号调理(如热电偶、压力、重量感测)
  • 仪表放大器、数据采集前端
  • 精密基准缓冲、低频滤波与积分电路
    注意:因 GBP 与压摆率属于中等水平,器件更适用于低频或直流精度场合,不建议用于高速大带宽信号链路。

四、封装与订购信息

  • 封装:SOP-8,标准引脚兼容常见运放布板布局
  • 订购后缀:TR = Tape & Reel(卷带包装),适合 SMT 自动化生产
    如需散装或其他包装形式,请联系华冠或授权分销商确认。

五、设计与使用建议

  • 电源旁路:建议在电源引脚到地各并联 0.1 μF 与 10 μF 陶瓷/电解电容以抑制高频噪声与提高稳定性。
  • 输入保护:避免输入引脚出现超出电源轨的电压,必要时加限流电阻或二极管保护。
  • 布线布局:对低噪声应用,减小输入引线长度,使用星形地或单点接地以降低共模干扰。
  • 温漂校准:即使 Vos 很小,长时间或高精度系统建议作温度漂移补偿或出厂校准。
  • 负载与输出:在驱动低阻抗负载或需更大驱动能力时,注意器件输出能力及热耗散。

六、总结

OP07M/TR 是一款面向高精度、低噪声直流信号处理的单路运放,兼具极低输入失调与优秀的共模抑制能力,封装适合批量贴片生产。适用于仪表、传感器前端与高精度放大电路的设计选型。在电源管理与 PCB 布局上采取适当防护与旁路措施,可发挥其最佳性能。若需更详细的电气特性曲线、引脚排列与典型应用电路图,请索取华冠 OP07M/TR 的完整数据手册。

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
