OP07CN 产品概述

OP07CN(品牌:HGSEMI / 华冠,封装:DIP-8)是一款针对精密直流信号处理优化的单路运算放大器。该器件以极低输入失调、电压噪声与优异的共模抑制能力著称,适用于高精度放大、传感器信号调理和精密仪表电路。

一、主要参数

  • 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(典型值)
  • 放大器数:单路
  • 输入偏置电流 (Ib):6.7 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):50 pA/℃
  • 压摆率 (SR):170 V/ms
  • 静态电流 (Iq):2.7 mA
  • 允许电源范围(双电源):Vee ~ Vcc = -3 V ~ +22 V
  • 输入失调电压温漂 (Vos TC):500 nV/℃
  • 输入失调电流 (Ios):6 nA

二、主要特性

  • 极低的输入失调电压和温漂,使直流精度出色,减少外部零点校准需求。
  • 高共模抑制比(120 dB)在共模干扰环境下仍能保持输出准确,适合差分测量。
  • 低噪声(10 nV/√Hz)适合对微小信号放大,如热电偶、微伏级传感器。
  • 中等带宽(GBP 500 kHz)与较高压摆率(170 V/ms)平衡了直流精度与瞬态性能。
  • 低静态电流(2.7 mA)在需要一定电源效率的精密设备中表现良好。

三、典型应用

  • 精密放大器与差分放大电路(仪表放大器前级)
  • 传感器信号调理(温度、压力、应变片等)
  • 精密比较和基准放大电路
  • 低频滤波器、积分器与直流耦合放大器
  • 医疗电子和测试测量设备中的低漂移放大单元

四、封装与引脚说明

  • 封装形式:DIP-8,便于面包板与通孔焊接使用,适合实验与一些传统设备。
  • 引脚排列与常见 OP07 系列兼容,便于替换与设计迁移(具体引脚图请参考厂家数据手册)。

五、使用建议与注意事项

  • 保证电源差不超过 44 V,且工作在推荐电源范围内(Vee ~ Vcc = -3 V ~ +22 V),以免损坏器件。
  • 在高精度应用中建议做良好电源去耦和输入保护,避免大差分输入或输入反向电压。
  • 若需要达到最小失调与最低漂移,可在电路中加入偏置调零电路或使用外部校准。
  • 注意温度系数(Vos TC、Ios TC)对长期稳定性的影响,关键应用可做温度补偿或选择恒温环境。

六、总结

OP07CN(HGSEMI/华冠,DIP-8)是一款面向精密直流和低频信号处理的低漂移、低噪声单路运算放大器。其高 CMRR 和小失调、良好的温漂特性,使其在仪表放大、传感器调理与精密测量等场景中具有良好竞争力。选型与应用时,请结合电源范围、温度环境与带宽需求进行权衡。

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
