WS72358M-8/TR 双路轨到轨运算放大器产品概述

WS72358M-8/TR是韦尔半导体(WILLSEMI)推出的一款低功耗双路运算放大器,针对便携电子、工业传感、电池供电系统等场景优化,兼具宽电源范围、轨到轨输入输出、超低偏置电流等核心特性,为信号调理提供高性价比解决方案。

一、产品定位与核心优势

该器件定位于中低频率信号放大与调理,核心优势集中在以下几点:

  1. 双路集成设计:单封装内置两路独立运放,节省PCB空间,降低系统成本;
  2. 轨到轨输入输出:输入可接近电源轨(Vdd/Vss),输出能驱动至电源轨附近,最大化信号动态范围;
  3. 超低功耗:总静态电流仅42μA,适配电池供电的便携设备(如智能穿戴、无线传感器节点);
  4. 高阻抗输入适配:输入偏置电流/失调电流仅10pA,适合高阻抗传感器(如电容式、压电式)的信号采集;
  5. 工业级宽温:工作温度覆盖-40℃~+125℃,满足 harsh 环境下的稳定运行;
  6. 抗干扰能力强:共模抑制比(CMRR)达110dB,有效抑制共模噪声干扰。

二、关键性能参数详解

1. 电源特性

  • 单电源工作范围:1.8V~5.5V,覆盖常见电池电压(如3.7V锂电池、5V USB供电);
  • 双电源最大宽度:Vdd-Vss≤9V(对应±4.5V双电源),兼容双电源系统设计;
  • 轨到轨IO:输入共模范围包含电源轨(Vss至Vdd),输出电压摆幅接近电源轨(典型值95%电源范围),避免信号削波。

2. 输入特性

  • 输入失调电压(Vos):3mV(典型值),满足一般信号调理的精度需求;
  • 失调电压温漂:1.1μV/℃,温度变化对输出精度影响小,适合宽温环境;
  • 输入偏置电流(Ib)/失调电流(Ios):均为10pA(典型值),超低偏置电流确保高阻抗输入时信号无明显衰减,适配电容式传感器、高阻信号源;
  • 共模抑制比(CMRR):110dB(典型值),对电源噪声、环境共模干扰的抑制能力强。

3. 交流与输出特性

  • 增益带宽积(GBP):1.5MHz,适合10kHz以下信号的放大(如音频、低频传感器信号);
  • 压摆率(SR):1.1V/μs,满足中等速度信号的响应需求;
  • 输出电流:46mA(典型值),可驱动小功率负载(如LED、小扬声器)或长线传输,避免负载效应;
  • 噪声密度:30nV/√Hz@1kHz,低噪声特性适合微弱信号放大(如生物电信号、微弱传感器信号)。

三、封装与环境适应性

WS72358M-8/TR采用MSOP-8封装,尺寸紧凑(典型尺寸2.9mm×3.0mm×1.0mm),适合高密度PCB布局;同时支持表面贴装工艺,便于自动化生产。

工作温度范围覆盖**-40℃~+125℃**,符合工业级器件标准,可稳定运行于高温(如汽车电子、工业现场)或低温(如户外传感节点)环境,无需额外散热或保温设计。

四、典型应用场景

  1. 便携电子设备:智能手环、蓝牙耳机、无线耳机的音频前置放大、传感器信号调理(如心率、加速度传感器);
  2. 工业传感系统:压力传感器、温度传感器、流量传感器的信号放大与滤波,适配宽温工业环境;
  3. 电池供电系统:低功耗无线传感节点、便携式医疗设备(如血糖监测仪)的信号调理,延长电池续航;
  4. 消费电子:小型音频设备(如蓝牙音箱)的前置放大、耳机驱动;
  5. 医疗电子:微弱生物电信号(如心电图、肌电图)的放大,低噪声特性确保信号清晰度。

WS72358M-8/TR通过平衡性能与成本,为多领域信号调理提供了可靠的集成化解决方案,适合对功耗、空间、宽温有要求的应用场景。

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
