上海矽朋(Siproin)推出的SSP1120是一款16位高精度Sigma-Delta模数转换器(ADC),专为工业级低功耗信号采集场景设计,集成多通道差分输入、内置基准/温度传感器等功能,适配电池供电及宽温环境应用。
SSP1120以16位分辨率为核心,兼顾精度与采样速率:
采用SPI串行接口,与主流MCU(如STM32、ATmega系列)兼容,仅需4根线(SCK、MOSI、MISO、CS)即可实现数据传输,布线简单且占用IO资源少。
支持内置+外置双时钟模式:
SSP1120内置多项实用功能,减少外部元件数量,简化电路设计:
内置基准电压源,温漂系数仅5ppm/℃,在-40℃~125℃宽温范围内保持电压稳定,无需外部精密基准即可实现高精度转换。
支持增益可调,可针对不同幅度的输入信号(如mV级小信号)进行放大,避免信号丢失,扩展输入信号范围。
集成片上温度传感器,可实时监测芯片工作温度,无需额外添加温度传感器即可实现系统热管理,提升可靠性。
工作电压覆盖2.3V~5.5V,兼容3.3V、5V主流系统电源,也适配电池供电(如2节AA电池、锂电池)场景。
静态电流仅50nA,在休眠模式下可长期保持低功耗,适合电池供电的便携式设备(如无线传感器节点),大幅延长续航时间。
支持**-40℃~+125℃**工业级宽温,可在户外、车载、工业现场等恶劣环境下稳定工作。
采用TSSOP-16贴片封装,体积小(5.2mm×4.4mm),适配高密度PCB设计,焊接工艺成熟,易实现批量生产。
SSP1120的性能与功能匹配多类低功耗信号采集需求:
总结:SSP1120是一款高性价比的16位Sigma-Delta ADC,集成度高、功耗低、宽温适配,适合工业及消费电子领域的信号采集场景,可有效简化电路设计并提升系统可靠性。

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.
