XL620 仪表放大器(单路)产品概述

一、产品简介

XL620 是 XINLUDA(信路达)推出的一款单路仪表放大器,采用 SOP-8 封装,专为精密传感信号调理设计。器件结合高共模抑制、高精度低漂移及低噪声特性,适用于桥式传感器、低电平差分信号放大与精密数据采集前端。

二、主要性能指标

  • 放大器数:单路
  • 共模抑制比(CMRR):90 dB(高共模抑制,提升差分测量稳定性)
  • 输入偏置电流(Ib):500 pA
  • 输入失调电流(Ios):100 pA
  • 输入失调电压(Vos):30 μV
  • 输入失调电压温漂(Vos TC):300 nV/℃
  • 增益带宽积(GBP):2.038 MHz
  • 压摆率(SR):1.2 V/μs
  • 输出电流:最大 18 mA
  • 静态电流(Iq):约 900 μA
  • 噪声密度(eN):17 nV/√Hz @ 1 kHz
  • 工作温度:-40 ℃ ~ +85 ℃
  • 电源范围:单电源 4.5 V ~ 38 V,或对称双电源 ±2.25 V ~ ±19 V(最大电源宽度 38 V)
  • 电源纹波抑制比(PSRR):111 dB
  • 封装:SOP-8

三、核心优势

  • 高精度:30 μV 的低输入失调电压与 300 nV/℃ 的低温漂,保证长期测量的稳定性。
  • 优秀共模抑制:90 dB 的 CMRR 在共模电压变化或长线差分采集时能有效抑制干扰。
  • 低噪声、低偏流:17 nV/√Hz 的噪声密度与皮安级偏置电流适合微弱传感器信号放大。
  • 宽电源兼容性:单/双电源宽范围支持,便于在多种系统电源架构中集成。
  • 低功耗且驱动能力适中:900 μA 静态电流与 18 mA 的输出驱动,平衡了功耗与负载能力。

四、典型应用场景

  • 力、压力、称重传感器(应变计/桥式传感器)前端放大
  • 生物电信号采集(低频微弱差分信号)
  • 精密数据采集系统(ADC 前置放大)
  • 工业过程控制与传感器调理
  • 温度传感(与热电偶/RTD 搭配)等需要高 CMRR 与低漂移的场合

五、使用建议与注意事项

  • 参考数据手册配置增益元件:XL620 支持通过外部元件设置放大倍数(具体增益连接请参照产品手册)。
  • 布局与去耦:电源引脚靠近封装放置去耦电容(如 0.1 μF 与 10 μF 并联),以保证高 PSRR 实际表现。
  • 输入保护与滤波:在输入端加入小阻值串联与差分滤波电容,可抑制瞬态并降低噪声带宽。
  • 接地与屏蔽:差分输入线尽量采用短线和屏蔽,敏感应用可使用导体防护(guard)以降低偏置电流带来的误差。
  • 温度补偿:对高精度系统建议进行环境温漂校准或采用恒温设计以发挥低 Vos TC 优势。
  • 注意最大输出驱动与电源范围,避免超出器件极限工作条件。

六、封装与订购信息

  • 品牌:XINLUDA(信路达)
  • 型号:XL620
  • 封装:SOP-8(适合通用 PCB 安装与自动贴装工艺)
  • 若需样片、技术手册或参考电路,请联系厂商授权分销或代理获取完整数据手册与应用笔记。

XL620 以其低失调、低噪声及宽电源兼容性,适合对精度和稳定性有较高要求的传感器前端与数据采集应用,是工业与精密测量领域的可靠选择。

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
