XL7650-8 产品概述

XL7650-8 是信路达(XINLUDA)推出的一款高精度单路运算放大器,针对精密测量与高共模干扰抑制场合设计。器件在低失调、超高共模抑制以及极低输入偏置电流方面表现优异,适合传感器前端、差分放大、精密滤波与仪表放大器等应用。

一、主要性能特点

  • 极高共模抑制比(CMRR):140 dB,适合强共模干扰环境下仍要求高差模增益精度的系统。
  • 超低输入失调电压(Vos):5 µV,配合温漂低(8 µV/℃),适合长期稳定测量。
  • 极低输入偏置电流(Ib):20 pA,输入失调电流(Ios):8 pA,适用于高阻抗传感器和微安级信号链。
  • 增益带宽积(GBP):2 MHz,压摆率(SR):2.5 V/µs,满足中等带宽的精密放大需求。
  • 低静态电流(Iq):2 mA,输出驱动能力可达 4.5 mA,适合便携与低功耗系统。
  • 电源范围:双电源工作电压 4.5 V ~ 16 V(最大电源差 16 V),灵活支持单电源或对称电源应用。
  • 工作温度范围:0 ℃ ~ +70 ℃;封装:SOP-8;单路放大器结构。

二、典型应用场景

  • 精密仪表放大器与差分放大器(利用高 CMRR 减少共模误差)。
  • 应变片、热电偶等高阻抗传感器的前置放大器(受益于超低 Ib/Ios)。
  • 精密积分器、低频滤波器和采样保持电路。
  • 精密数据采集系统的信号调理、ADC 驱动与差分信号转换。
  • 低功耗便携测量设备与工业控制接口电路。

三、电气规格要点(摘要)

  • 共模抑制比(CMRR):140 dB
  • 最大电源宽度(Vdd - Vss):16 V
  • 输入失调电压(Vos):5 µV;温漂 8 µV/℃
  • 输入偏置电流(Ib):20 pA;输入失调电流(Ios):8 pA
  • 增益带宽积(GBP):2 MHz;压摆率(SR):2.5 V/µs
  • 静态电流(Iq):2 mA;输出电流:4.5 mA
  • 封装:SOP-8;单路放大器;工作温度 0 ℃~+70 ℃

四、封装与装配建议

  • 建议采用标准 SOP-8 PCB 布局,电源引脚旁放置 0.1 µF 陶瓷去耦电容,尽量靠近引脚焊盘以抑制电源瞬态。
  • 对于超低偏置电流应用,需注意 PCB 表面洁净与防潮处理,采用 guard 环路或隔离槽以减小泄漏电流对测量的影响。
  • 输入端尽量避免长导线与高阻抗环路,必要时采用屏蔽和差分布线。

五、设计注意事项

  • 虽然器件具有高 CMRR,但在实际电路中仍应保证良好对称布局和匹配阻抗以获得最佳性能。
  • 在高精度测量中,配合低温漂电阻和多点校准可进一步降低系统误差。
  • 输出驱动能力有限(4.5 mA),在驱动低阻负载或长电缆时需注意输出压降与线性度。

六、采购与技术支持

XL7650-8 由信路达(XINLUDA)提供,封装为 SOP-8,适用于批量生产与样片评估。对尺寸、引脚定义、典型电路(如差分放大、仪表放大器配置)有需求时,可参考厂商数据手册或联系技术支持获取完整电气特性曲线与应用指南。

如需更详细的电气参数曲线、典型应用电路或样片支持,请告知具体应用场景与电源/负载条件。

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
