SGM8250-1XN5G/TR 产品概述

一、产品简介

SGM8250-1XN5G/TR 是圣邦微(SGMICRO)推出的一款单通道高性能运算放大器,集成零漂移(Zero-Drift)技术,采用微功耗设计,提供轨到轨输入与轨到轨输出特性,适用于对直流精度和长期稳定性有较高要求的便携及工业测量系统。器件封装为 SOT-23-5,工作温度范围为 -40℃ 至 +125℃。

二、主要性能参数

  • 放大器数:1(单通道)
  • 输入/输出:轨到轨输入,轨到轨输出
  • 输入失调电压 Vos:10 μV(典型)
  • 输入失调电压温漂 Vos TC:110 nV/℃
  • 压摆率 SR:100 V/ms
  • 输入偏置电流 Ib:60 pA
  • 共模抑制比 CMRR:112 dB
  • 静态电流 Iq:45 μA(典型)
  • 输出电流:17 mA(典型)
  • 功能特性:零漂移 / 自动稳零
  • 工作温度:-40℃ ~ +125℃
  • 封装:SOT-23-5

三、核心优点与设计亮点

  • 超低失调与极小温漂:10 μV 的低输入失调配合 110 nV/℃ 的温漂,使得在低频或直流测量中能长期保持高精度,减少校准频率与维护成本。
  • 零漂移技术:内部自动稳零结构抑制低频噪声与 1/f 漂移,适合放大传感器微小直流信号。
  • 轨到轨输入输出:支持接近电源轨的输入与输出电平,提高在低电压供电系统中利用率。
  • 微功耗与合理输出能力:45 μA 的静态电流适合电池供电或低功耗应用,同时 17 mA 的输出驱动能力可直接驱动常见负载或后级电路。
  • 宽温度适应性:-40℃ 到 +125℃ 的工作温度覆盖工业级场景。

四、典型应用场景

  • 精密传感器信号调理(温度、应变计、压力等)
  • 数据采集前端与差分放大器
  • 医疗便携设备与仪表放大器
  • 低功耗电池供电的测量系统与便携仪器
  • 工业控制与过程测量中需要高直流精度的放大环节

五、封装与可靠性

SGM8250-1XN5G/TR 提供 SOT-23-5 小封装,适合空间受限的 PCB 设计与自动贴装流程。器件在工业温度等级范围内工作,符合长期可靠性要求。为获得最佳性能,建议按数据手册中的引脚接地与去耦规范布线,并在受干扰环境下适当增加滤波或屏蔽措施。

六、选型建议与使用要点

  • 若应用对直流精度、长期稳定性要求高且需低功耗,SGM8250 是合适选择。
  • 在高频或需要大驱动电流的应用场景,应评估压摆率与输出电流是否满足系统带宽与驱动需求。
  • 推荐在设计初期参考完整数据手册,确认电源电压范围、输出摆幅与输入共模范围的具体限制,以及输入保护与输出短路保护等细节。

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
