杭州瑞盟MS5194T 24位高精度ADC产品概述

一、核心性能参数总览

MS5194T是杭州瑞盟针对低速高精度测量场景推出的24位模数转换器(ADC),核心参数覆盖「高分辨率、多通道、灵活配置」三大方向,具体如下:

  • 分辨率:24位,可捕捉μV级微小信号;
  • 通道数:6通道差分输入,抗共模干扰能力强;
  • 采样率:4.17Hz,适配低速信号(如传感器稳态输出);
  • 时钟系统:内置64kHz振荡器,支持外置时钟扩展;
  • 基准电压:内置高精度基准(温漂5ppm/℃),兼容外置基准;
  • 功能扩展:支持可变增益、内置温度传感器;
  • 功耗与电压:静态电流仅400μA,工作电压范围2.7V~5.25V;
  • 工作温度:-40℃~+105℃,工业级宽温适配。

二、关键特性与实际优势

1. 高精度测量能力

24位分辨率搭配5ppm/℃的基准温漂,在宽温范围内仍能保持稳定精度。例如,对于10V满量程输入,温度每变化1℃,误差仅约0.5μV,可满足工业传感器(压力、温度)的长期稳定监测需求。

2. 灵活的配置兼容性

  • 时钟选择:内置64kHz振荡器无需外部晶振,简化电路设计;外接时钟可适配系统特定时序,兼顾成本与灵活性;
  • 基准选择:内置基准直接可用(省元件),外置基准支持更高精度(如1ppm/℃级),适配不同性能要求;
  • 可变增益:支持信号放大/衰减,适配05V、010V等输入范围,小信号(如mV级)可通过增益放大后精准采集。

3. 低功耗与宽电压适配

静态电流仅400μA,结合2.7V~5.25V宽电压,可适配电池供电的便携式设备(如手持测量仪),或工业现场宽波动电源(如24V转5V非稳压电源)。

4. 内置温度传感器简化设计

无需额外添加温度传感器,可直接读取芯片自身温度,用于信号温度补偿(如压力传感器的漂移修正),减少BOM成本与PCB空间。

三、封装与工作环境

MS5194T采用TSSOP-24封装,体积小巧(约5mm×4.4mm),适合小型化设备(智能传感器模块、便携式仪器)。-40℃~+105℃的宽温范围,可在户外环境、车载辅助模块等 harsh 场景稳定运行。

四、典型应用场景

  1. 工业过程监测:压力变送器、温度传感器、流量传感器的信号采集(化工、电力管道监测);
  2. 便携式测量仪器:手持万用表、环境检测仪(温湿度、气体浓度),依赖低功耗与宽电压;
  3. 汽车电子辅助模块:车载传感器扩展(胎压、电池状态监测),适配宽温要求;
  4. 医疗设备:低功耗生理信号采集(心电图、血压监测),需高精度与稳定性能;
  5. IoT智能节点:环境监测节点(集成6通道采集+温度补偿),减少外部元件。

五、应用注意事项

  • 追求最高精度时,建议外接1ppm/℃级基准,降低温漂影响;
  • 可变增益需匹配输入信号幅度(如<100mV信号设10倍增益),避免溢出;
  • 电源端添加10μF电解+0.1μF陶瓷电容滤波,抑制噪声干扰;
  • 差分输入需注意信号布线(远离高噪声电路),减少共模干扰。

MS5194T通过「高分辨率+灵活配置+低功耗」的组合,精准覆盖工业、便携、医疗等多领域的低速高精度测量需求,是小型化智能传感器系统的优选ADC。

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
