AD8138ARZ-R7 产品概述

一、概述

AD8138ARZ-R7 是一款单路高速差分放大器,专为高性能 ADC 驱动与数据采集前端设计。器件由 ADI / Linear 提供,采用 8-SOIC 封装,集成差分输出,适用于对带宽、失真和噪声有严格要求的系统。

二、主要特性

  • 放大器数:单路
  • 输出类型:差分,适合直接驱动差分 ADC
  • 增益带宽积 (GBP):320 MHz
  • 压摆率 (SR):1150 V/µs,支持大幅快速信号边沿
  • 噪声密度:5 nV/√Hz(100 kHz–40 MHz)
  • 输入失调电压 (Vos):1 mV,温漂 4 µV/℃
  • 输入偏置电流 (Ib):4 µA
  • 静态电流 (Iq):20 mA,输出电流可达 95 mA
  • 共模抑制比 (CMRR):-77 dB(器件数据标注)
  • 电源纹波抑制比 (PSRR):90 dB
  • 最大电源宽度:Vdd–Vss = 11 V
  • 单电源工作:2.7 V ~ 11 V;双电源工作:±1.4 V ~ ±5.5 V
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 稳定时间:16 ns

三、典型应用

适用于高速数据采集与 ADC 驱动、电信接收链、仪器仪表、医疗成像前端、射频/视频信号处理等需要低噪声、高线性差分驱动的场合。

四、设计与使用建议

  • 电源去耦:为保证低噪声和高 PSRR,建议在电源引脚附近放置快速陶瓷电容与大容量钽电容组合去耦。
  • 共模管理:差分输出接入 ADC 时应注意共模电平匹配,必要时通过直流耦合或交流耦合电容和匹配电阻实现。
  • 热管理与封装:8-SOIC 封装热阻有限,高静态电流与输出负载下注意 PCB 散热与走铜。
  • 布局:差分对走线长度匹配、保持阻抗连续,输入端使用短回路尽量减小寄生电感与电容。

五、封装与型号信息

  • 型号:AD8138ARZ-R7
  • 品牌:ADI(Analog Devices / Linear)
  • 封装:8-SOIC,适合中小批量贴片组装与自动化生产。

六、总结

AD8138ARZ-R7 提供高带宽、高压摆率与低噪声的差分驱动能力,兼具宽电源范围与良好温漂性能,是对接高速 ADC 与高性能数据采集系统的理想前端放大器。选择与布局得当,可在宽温度与各种供电模式下稳定工作,满足严苛的模拟前端设计需求。

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
