WS72552M-8/TR 产品概述

一、简介

WS72552M-8/TR 是 WILLSEMI(韦尔)推出的一款双路零温漂运算放大器,采用 MSOP-8 封装,针对高精度、低漂移和低噪声的信号处理场景设计。器件支持轨到轨输入与轨到轨输出,适用于狭窄电源、电池供电及工业级温度环境(-40℃ ~ +125℃),在精密测量与数据采集系统中表现出色。

二、主要性能指标

  • 放大器数:双路
  • 最大电源电压差 (VDD–VSS):9 V(推荐单电源工作范围:2.5 V ~ 5 V)
  • 轨到轨:输入与输出均为轨到轨结构
  • 增益带宽积 (GBP):1.7 MHz
  • 输入失调电压 (VOS):14 μV
  • 失调电压温漂 (VOS TC):8 nV/℃
  • 压摆率 (SR):1.2 V/μs
  • 输入偏置电流 (IB):10 pA
  • 输入失调电流 (IOS):4 pA
  • 噪声密度 (eN):80 nV/√Hz(@1 kHz)
  • 共模抑制比 (CMRR):140 dB
  • 静态电流 (Iq):235 μA(每对)
  • 输出电流:±20 mA(典型)
  • 工作温度范围:-40℃ ~ +125℃
  • 封装:MSOP-8

三、核心特性

  1. 零温漂性能:14 μV 的超低输入失调配合 8 nV/℃ 的极小温漂系数,保证在宽温区间内长期稳定的直流精度,适合高精度直流测量与传感器前端。
  2. 轨到轨输入/输出:支持接近电源轨的信号处理,提高在低电压单电源系统中的动态范围与设计灵活性。
  3. 低噪声与低偏置:80 nV/√Hz 的噪声密度以及 pA 级偏置电流,适合高阻抗源与微小信号放大,降低误差来源。
  4. 低功耗与适度驱动能力:235 μA 的静态电流适合便携与长寿命电源应用,同时 20 mA 的输出驱动能力足以驱动常见采样电路与模拟负载。

四、典型应用场景

  • 精密传感器接口:压力传感器、温度传感器、应变计与荷重传感器放大器
  • 仪表与数据采集:高精度 ADC 驱动、差分信号转换、单端/差分测量前端
  • 医疗与生命监测设备:低频、生物电信号放大器(需注意带宽与滤波设计)
  • 电池供电与便携设备:低压单电源工作(2.5 V 起)与低功耗要求场景
  • 精密滤波与低速控制回路:有零漂要求的积分器、PI 控制器与慢变化信号处理

五、封装与订购信息

  • 封装形式:MSOP-8(小尺寸、便于高密度 PCB 布局)
  • 型号:WS72552M-8/TR(带托盘或卷带/卷轴包装根据订单而定)
  • 工作温度等级:工业级(-40℃ ~ +125℃),满足严苛环境需求

六、设计建议与注意事项

  • 电源与旁路:为发挥低噪声与低漂移特性,建议在供电引脚处使用紧邻封装的高频旁路电容(如 0.1 μF)并配合较大电容进行低频滤波。
  • 带宽与稳定性:GBP 1.7 MHz 与 1.2 V/μs 的压摆率适合低频到中低频精密放大,若用于高增益或高速脉冲信号需关注相位裕量与补偿。
  • 输入保护:轨到轨结构允许接近电源轨输入,但仍需注意超出电源轨的输入电压或静电放电保护。
  • 温度漂移管理:器件本身温漂极低,但系统级精度仍受外部电阻、电源和温度梯度影响,建议在关键电阻与信号通路处采用阻值低温漂元件并做好热源隔离。

WS72552M-8/TR 凭借零温漂、超低失调与高共模抑制等特性,在要求高直流精度与稳定性的测量与控制系统中具有显著优势,尤其适合对长期漂移和微小信号放大敏感的应用场合。若需进一步的电气特性曲线、典型应用电路或封装尺寸图,可根据具体需求提供详细资料。

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
