SSP1120 16位Sigma-Delta ADC产品概述

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。

一、核心性能参数

SSP1120以16位分辨率为核心,兼顾精度与采样速率:

  • 分辨率:16位,支持无失码转换,确保信号采集的线性度;
  • 采样率:最大2kHz,适配温度、压力、应变等慢变模拟信号的实时监测;
  • 输入通道:2路差分输入,有效抑制共模干扰(如电源噪声、空间电磁干扰),提升弱信号采集的信噪比;
  • 架构:Sigma-Delta调制+数字滤波,通过过采样技术降低量化噪声,进一步优化精度。

二、灵活的接口与时钟配置

1. 接口类型

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。

2. 时钟方案

支持内置+外置双时钟模式:

  • 内置时钟:默认4.096MHz,与内置基准电压匹配,无需外部晶振即可快速部署;
  • 外置时钟:频率范围500kHz~4.5MHz,可根据系统需求灵活调整,适配不同采样率或时钟同步场景。

三、集成化功能模块

SSP1120内置多项实用功能,减少外部元件数量,简化电路设计:

1. 高精度基准电压源

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。

2. 可变增益放大器(VGA)

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。

3. 内置温度传感器

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。

四、低功耗与宽电压适配

1. 电源电压范围

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。

2. 功耗表现

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。

五、工业级环境与封装

1. 工作温度范围

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。

2. 封装形式

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。

六、典型应用场景

SSP1120的性能与功能匹配多类低功耗信号采集需求:

  • 工业传感器:温度、压力、液位等慢变信号采集;
  • 便携式设备:电池供电的无线监测节点;
  • 车载系统:低功耗环境监测模块;
  • 智能家居:传感器数据采集终端。

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。

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.

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
