LM224 产品概述

一、产品简介

LM224 是由 HXY MOSFET(华轩阳电子)推出的四路运算放大器,封装为 SOP-14,面向需要多通道放大且功耗受控的通用模拟前端应用。器件在单电源和双电源供电下均能稳定工作,适用于信号调理、低频滤波、传感器接口与驱动小负载等场景。

二、主要电气参数

  • 放大器数:4 路(四合一封装)
  • 最大电源电压(Vdd–Vss):20 V
  • 单电源工作范围:3 V ~ 20 V
  • 双电源工作范围(Vee ~ Vcc):-1.5 V ~ 10 V
  • 输入失调电压(Vos):7 mV(典型)
  • 输入偏置电流(Ib):250 nA(典型)
  • 输入失调电流(Ios):50 nA(典型)
  • 共模抑制比(CMRR):80 dB(典型)
  • 器件静态电流(Iq,四路合计):600 µA
  • 输出电流能力:峰值约 40 mA
  • 工作温度范围:0 ℃ ~ +70 ℃
    注:描述中提及“100 dB”通常用于指示器件的开环电压增益或在特定条件下的额定值,用户在关键设计中请参照实际器件规格表确认。

三、性能特点与设计要点

  • 低静态功耗:四路总静态电流约 600 µA,适合电池供电或低功耗系统。
  • 中等输入偏置与失调:Vos ≈ 7 mV、Ib ≈ 250 nA,满足多数精密但非超高精度的传感器接口;若需更高精度,可通过外部偏置校准减小失调影响。
  • 宽供电范围:支持从 3 V 单电源到 ±10 V 双电源,便于在多种系统电压下使用。
  • 输出驱动能力:40 mA 的输出电流适合驱动小型继电器驱动、指示灯或直接驱动低阻抗负载,需注意热耗与输出摆幅限制。
  • 共模输入范围与 CMRR:80 dB 的共模抑制比在工业与消费类应用中属中等水平,差分与共模干扰抑制需通过布局与滤波完成。

四、典型应用场景

  • 传感器信号调理(电压放大、差分放大)
  • 低通/高通/带通滤波器的多路实现
  • 模拟开关驱动与缓冲放大
  • 多通道数据采集前端、信号并联/比较电路

五、使用建议与注意事项

  • 电源去耦:建议在靠近器件的 Vcc/Vee 引脚并接 0.1 µF 陶瓷电容与 10 µF 电解电容,以抑制电源噪声与瞬态。
  • 输入保护:若输入可能超过电源范围,应采用限流电阻与钳位二极管保护输入级,避免失调电流和内部晶体管受损。
  • 温度与漂移:器件标称工作温度 0~70 ℃,在更严苛温度下请选用相应等级或额外校准。
  • PCB 布局:模拟与数字地分离、短回流路径和良好接地能显著提升 CMRR 与抑制干扰。
  • 校准与补偿:对失调与偏置敏感的测量电路建议在系统级进行零点与增益校准。

六、封装与采购信息

  • 封装形式:SOP-14,适合自动化贴片与中等密度 PCB 布局。
  • 品牌:HXY MOSFET(华轩阳电子);建议在采购前向供应商确认封装管脚映射与完整规格书,包含典型特性曲线与封装尺寸图。

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
