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。
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。
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。
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。

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.
