SGM8968-1XN5G/TR 产品概述
一、性能概览
SGM8968-1XN5G/TR 是 SGMICRO（圣邦微）推出的高精度单路运算放大器，封装为 SOT-23-5。器件支持轨到轨输入与轨到轨输出，适用于低压和电池供电系统。主要电气参数包括：增益带宽积（GBW）10 MHz、输入失调电压 Vos 典型 50 μV、温漂 Vos TC 仅 1 μV/℃、压摆率 SR 20 V/μs、输入偏置电流 Ib 与失调电流 Ios 均为 6 pA 量级、输入电压噪声密度 eN 约 8 nV/√Hz（@10 kHz）、共模抑制比 CMRR 95 dB、静态电流 Iq 1.6 mA、输出驱动能力可达 80 mA。工作温度范围 -40 ℃ 至 +125 ℃。供电方面支持单电源 1.8 V ～ 5.5 V，并可在双电源模式下工作于约 ±0.9 V ～ ±2.75 V 范围。器件具备 ESD 保护。
二、关键优势
- 超低失调与低温漂：Vos 50 μV、1 μV/℃ 的温漂，适合精密测量与零漂要求高的前端放大。
- 极低输入偏置电流：6 pA 级别，利于高阻抗传感器、霍尔元件或电容式传感器接口。
- 轨到轨输入/输出：在低电源电压下仍能充分利用输入与输出摆幅，利于单电池系统设计。
- 良好瞬态性能：20 V/μs 的压摆率与 10 MHz 的 GBW，满足中速信号放大与滤波要求。
- 较强驱动能力：80 mA 输出电流可直接驱动低阻抗负载或作为缓冲放大器使用。
三、典型应用
- 精密传感器前端、差分信号放大与信号调理
- ADC 驱动与采样保持电路
- 便携式医疗、手持测量仪器与工业数据采集
- 主动滤波器、缓冲器、低噪声放大器
- 电源管理与参考放大场合
四、使用与布局建议
- 电源去耦：距离器件尽量靠近放置 0.1 μF 与 1 μF 组合电容以抑制瞬态噪声。
- 输入保护：尽管具备 ESD 保护，但在强干扰或可能过压场合应增加限流或钳位措施。
- 热设计：Iq 为 1.6 mA，单通道功耗随供电电压增加，请注意在高温或多器件密集布局时的散热。
- 布线注意：为保证低噪声与高精度，输入引脚采用短线并与噪声源隔离，模拟地采用单点接地策略。
五、封装与订购
封装：SOT-23-5，适合表贴组装与空间受限应用。型号：SGM8968-1XN5G/TR，由 SGMICRO（圣邦微）提供，适用于需要高精度、低失调和低功耗的便携与工业级系统。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
