HG8552CM/TR 产品概述

HG8552CM/TR 是华冠(HGSEMI)推出的一款高精度、低漂移的双通道零漂移运算放大器,采用 SOP-8 封装,面向对直流精度和低噪声有较高要求的测量与信号调理应用。器件支持轨到轨输入与轨到轨输出(RRIO),并具有宽泛的单/双电源工作范围与极低的输入偏移与噪声特性,适合电池供电和工业级应用。

一、主要特性

  • 零漂移架构,极低输入失调电压:典型 Vos = 5 μV,失调温漂 Vos TC = 50 nV/℃
  • 极小输入偏置电流:Ib = 20 pA,输入失调电流 Ios = 10 pA
  • 低噪声性能:噪声密度 eN = 49 nV/√Hz(@1 kHz)
  • 共模抑制比(CMRR):110 dB(高直流精度保证)
  • 轨到轨输入与轨到轨输出(RRIO),适配低电源电压系统
  • 宽电源工作范围:单电源 2.1 V ~ 5.5 V,双电源 ±1.05 V ~ ±2.75 V,最大电源宽度 (Vdd–Vss) = 5.5 V
  • 增益带宽积(GBP)= 1.5 MHz,压摆率(SR)= 0.84 V/μs,输出驱动电流可达 30 mA
  • 静态电流 Iq = 320 μA/通道(双通道器件整体功耗低)
  • 工作温度范围:-40 ℃ ~ +125 ℃

二、电气参数摘要

  • 输入失调电压 (Vos):5 μV(典型)
  • 输入失调电压温漂 (Vos TC):50 nV/℃
  • 输入偏置电流 (Ib):20 pA;输入失调电流 (Ios):10 pA
  • 共模抑制比 (CMRR):110 dB
  • 噪声密度 (eN):49 nV/√Hz @1 kHz
  • 增益带宽积 (GBP):1.5 MHz;压摆率 (SR):0.84 V/μs
  • 输出电流能力:30 mA;静态电流 (Iq):320 μA/通道

三、优势与设计要点

  • 高直流精度:极低的 Vos 与极小的温漂使 HG8552CM/TR 在精密直流放大、仪表放大器前端及差分测量中表现优异,减少外部校准需求。
  • 低噪声与 RRIO:49 nV/√Hz 的噪声密度结合轨到轨输入/输出,适合低电压单电源系统和微弱信号采集(如热电偶、应变片放大)。
  • 适度带宽与稳定性:1.5 MHz 的 GBP 适合低频到中频信号处理,零漂移架构在低增益下稳定性良好。设计外围回路时建议考虑补偿与合理的反馈网络以防止振荡。
  • 电源与保护:器件支持 2.1 V 单电源最低工作电压,适合低功耗电池应用。系统设计时建议在电源引脚加旁路电容(如 0.1 μF 与 1 μF 并联)以保证瞬态稳定,必要时加输入限流或保护二极管以防高压差或反接。

四、典型应用场景

  • 精密传感器接口:压力传感器、应变计、热电偶放大器
  • 数据采集前端:低漂移信号调理、差分放大、滤波器实现
  • 工业控制与测量设备:长时间稳定测量、远端传感器放大
  • 便携式医疗与仪表:低功耗、低电压供电的高精度放大电路

五、封装与订货信息

  • 型号:HG8552CM/TR
  • 品牌:HGSEMI(华冠)
  • 封装:SOP-8(双通道)
  • 交付形式:TR(卷带包装,适合贴片生产线)

六、应用建议

  • 电源去耦:靠近 Vcc/Vee 引脚放置 0.1 μF 陶瓷和 1 μF 低ESR 电解/钽电容并联。
  • 输入保护:对于可能出现的高差分电压或反向极性情况,建议在输入端加入系列电阻或 TVS/钳位二极管。
  • 布局注意:模拟地与功率地分离,尽量缩短反馈回路与输入引脚的走线,减小噪声耦合。
  • 工作点选择:在需要最大带宽或更高瞬态响应时,注意增益配置与负载条件对压摆率与稳定性的影响。

总结:HG8552CM/TR 以其零漂移特性、超低失调与低噪声表现,结合 RRIO 与宽电源范围,是面向高精度低频测量与信号调理的理想双通道运算放大器。用户按上述设计要点布局与去耦,可在精密测量与低电压系统中获得可靠稳定的性能。

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.
