XD0832CC 产品概述

一、概述

XD0832CC 是信路达(XINLUDA)推出的一款 8 位、双通道、逐次逼近寄存器(SAR)型模数转换器(ADC),针对工业级和通用型数据采集场合而设计。器件支持差分输入结构,工作电压范围广(4.5V ~ 6.3V),工作温度覆盖 -40℃ 到 +85℃,并以 DIP-8 插件封装提供,便于开发与样机验证。

二、主要特性

  • 分辨率:8 位
  • 通道数:2 通道(可选择差分输入)
  • ADC 架构:SAR(逐次逼近)
  • 工作电压:4.5V ~ 6.3V
  • 时钟频率范围 (fc):10 kHz ~ 400 kHz(典型工作点 250 kHz)
  • 积分非线性(INL):最大 1 LSB
  • 静态电流:约 2 mA(器件静态消耗)
  • 温度范围:-40℃ ~ +85℃
  • 封装:DIP-8(便于面包板和手动焊接)

三、电气与环境指标

XD0832CC 以低至 2 mA 的静态电流使其在中低功耗应用中表现良好;在典型 5V 电源下静态功耗约为 10 mW。INL≤1LSB 保证了在 8 位分辨率下的线性精度,差分输入结构对共模干扰有较强抑制能力,适合较嘈杂的工业现场信号采集。器件的工作时钟允许用户在 10 kHz 至 400 kHz 之间灵活选取,典型建议使用 250 kHz 以在速度与抗扰性之间取得平衡。

四、典型性能与时序说明

作为 SAR ADC,XD0832CC 的一次完整转换通常需要约 N+1 个时钟周期(N=8),即 9 个时钟周期完成一次 8 位转换。以典型时钟 250 kHz 计算,单次转换时间约为 9 / 250 kHz ≈ 36 µs,对应最大采样率约 27.8 kS/s;使用更高时钟可提升转换速率(受系统时序与接口限制影响)。差分输入在实际系统中可用于提高抗共模噪声能力并扩大动态范围,但需配合稳健的参考电压与差分前端电路。

五、典型应用场景

  • 传感器数据采集(温度、压力、湿度等中低精度传感器)
  • 工业控制与监测(PLC 辅助采样、现场模拟量采集)
  • 测试与测量仪器(样机开发、教育与实验平台)
  • 电池与电源监控(电压/电流采样,需注意输入保护)
  • 小型嵌入式系统与人机界面(HMI)中对模拟信号的数字化处理

六、设计与布局建议

  • 电源与参考:使用低噪声 LDO 给 ADC 供电并对 VREF 做充分去耦,保证参考稳定是提高线性与噪声性能的关键。
  • 去耦与地线:在 VCC/AVCC 与 GND 之间靠近器件放置 0.1 µF 陶瓷旁路电容,并推荐增加 1 µF ~ 10 µF 的大电容滤波。模拟地与数字地尽量分割并在单点汇流。
  • 差分输入布线:保持差分对长度一致、绕组对称并尽量远离高速数字线,必要时使用共模 choke 或差分放大器。
  • 输入保护:在可能出现过压或反向电压的场合,加入限流电阻与 TVS/二极管保护,防止输入端损伤。
  • DIP-8 封装注意:通过孔焊接时注意热影响并保持良好接地回流。

七、封装与选型建议

XD0832CC 提供 DIP-8 封装,适合原型开发、教学和需要通过孔插装的产品设计。选型时应关注系统的采样速率需求(确认时钟频率与转换时间是否满足)与输入接口形式(差分/单端),并根据噪声与精度要求选择合适的参考源与前端滤波电路。

总结:XD0832CC 是一款适合中低速、工业温度范围内使用的 8 位双通道 SAR ADC,具备差分输入和低静态电流特性,适用于各类通用模数采集场景,尤其便于快速验证与原型开发。

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.
