意法半导体TSV992AIST运算放大器产品概述

TSV992AIST是意法半导体(ST)推出的一款双路轨到轨输入输出运算放大器,采用MSOP-8(8-MiniSO)紧凑型封装,针对工业级宽温环境、便携式设备及高阻抗信号放大场景优化设计,兼顾性能与功耗平衡。

一、产品基本定位与封装形式

TSV992AIST属于ST的TSV99x系列双运放,核心定位为中带宽、低功耗、宽温工业级放大器。其采用MSOP-8封装(尺寸约3mm×3mm),体积仅为传统DIP-8封装的1/4左右,非常适合对PCB空间有严格要求的应用(如便携式医疗设备、小型工业模块)。

二、关键性能参数解析

  1. 带宽与压摆率:增益带宽积(GBP)达20MHz,压摆率(SR)为10V/μs,可满足中等频率信号(如10kHz以下音频、低速传感器信号)的放大需求,避免信号失真;
  2. 直流精度:输入失调电压(Vos)典型值1.5mV,失调电压温漂仅2μV/℃,在宽温度范围内能保持稳定的直流性能,减少温变带来的信号误差;
  3. 输入特性:输入偏置电流(Ib)和输入失调电流(Ios)均为1pA(典型值),属于极低偏置水平,适合高阻抗输入源(如光电传感器、压电元件),可有效减少偏置电流在输入电阻上产生的电压误差;
  4. 抗干扰能力:共模抑制比(CMRR)达75dB,能有效抑制环境中的共模干扰(如电源噪声、电磁干扰),提升信号质量。

三、电源与工作温度范围

  • 电源适应性:支持单电源2.5V~5.5V供电,电源宽度(Vdd-Vss)最大可达5.5V,无需双电源即可实现轨到轨输入输出,简化电路设计;
  • 宽温可靠性:工作温度范围覆盖**-40℃~+125℃**,符合工业级温度要求,可稳定工作在 harsh环境(如户外传感器、汽车电子辅助模块)。

四、输入输出特性

TSV992AIST采用轨到轨输入+轨到轨输出设计:

  • 输入范围接近电源轨(可达到Vss+10mV~Vdd-10mV),能处理接近电源电压的小信号;
  • 输出摆幅接近电源轨(典型值Vss+50mV~Vdd-50mV),在单电源供电下可输出更大的信号幅度,无需额外电平转换电路;
  • 输出电流能力达35mA(典型值),可驱动中等负载(如小型继电器、LED指示灯、低阻抗耳机)。

五、噪声与静态功耗

  • 低噪声性能:10kHz处噪声密度仅21nV/√Hz,适合对噪声敏感的应用(如音频前置放大、微弱生物电信号放大);
  • 适中功耗:每通道静态电流约390μA(总静态电流780μA),在保持20MHz带宽的同时,兼顾了便携式设备的续航需求。

六、典型应用场景

TSV992AIST的参数特性使其适用于以下场景:

  1. 工业传感器信号放大:如温度、压力、流量传感器的信号调理,宽温范围与低偏置电流适配高阻抗传感器;
  2. 便携式医疗设备:如血糖监测仪、血氧仪的前置放大,小封装与低功耗满足便携需求;
  3. 音频前置放大:如耳机放大器、小型音响的信号放大,低噪声与轨到轨输出提升音质;
  4. 汽车电子辅助模块:如车身传感器信号处理,宽温与抗干扰能力适配车载环境;
  5. 电源管理电路:如电池电压监测、电流检测电路,轨到轨设计简化单电源供电。

总结:TSV992AIST是一款平衡性能、功耗与可靠性的双运放,紧凑型封装与宽温特性使其在工业、医疗、便携等领域具有广泛应用潜力,是替代传统运放的高性价比选择。

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
