SGM721XC5/TR 是圣邦微(SGMICRO)推出的一款单通道运算放大器,封装为 SC-70-5,工作电源范围为单电源 2.5V 至 5.5V,工作温度范围 -40℃ 至 +125℃。器件支持轨到轨输入与轨到轨输出,适合低电压单电源系统。核心参数包括:增益带宽积(GBW)10MHz,压摆率(SR)8.5V/µs,输入失调电压 4mV,失调电压温漂 2.1µV/℃,输入偏置电流与失调电流均为 1pA,输入电压噪声密度 8nV/√Hz(@1kHz),共模抑制比(CMRR)91dB,静态电流 Iq 约 970µA,输出驱动能力 约 57mA。
SGM721XC5/TR 为单通道放大器,SC-70-5 小封装利于空间受限设计,适用于便携与消费类电子产品。选型时请结合所需带宽、噪声、输入偏置及输出驱动能力权衡;针对极高精度(μV 级)场合,若需更低失调电压可考虑配合外部校准或使用零飘较小的专用放大器。
总结:SGM721XC5/TR 在轨到轨行为、低输入偏置、低噪声与中等带宽之间取得良好平衡,适合多种传感器接口与便携信号处理场景,是空间受限且要求低漂移低噪声的通用运放方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
