- 增益带宽积（GBW）：1 MHz
- 输入失调电压 (Vos)：2 mV（典型）
- 输入偏置电流 (Ib)：45 nA
- 输入失调电流 (Ios)：3 nA
- 共模抑制比 (CMRR)：85 dB
- 静态电流 (Iq)：500 μA（整芯片）
- 最大输出电流：40 mA
- 工作温度范围：0 ℃ ~ +70 ℃（商业级）
- 单电源电压：3 V ~ 30 V
- 双电源电压：±1.5 V ~ ±15 V（支持对称供电）
- 封装：SOP-8
三、性能特点
- 低静态功耗，适合电池供电或功耗受限的场合。
- 低输入失调与低偏置电流，有利于直流精度和高阻抗信号源的测量。
- 宽电源电压范围，支持从低压单电源到高压系统及对称电源应用。
- 适度的输出驱动能力（最高40 mA），可直接驱动小功率负载或后级驱动器。
四、典型应用场景
- 精密电压/电流测量前端放大器
- 传感器信号调理（如热电偶、应变片前置）
- 有源滤波器与积分/微分电路
- 基本模拟比较与门限检测、低速数据采集系统
- 工业控制、仪器仪表与消费类电子的模拟部分
五、封装与可靠性
GOODWORK LM2904 提供 SOP-8 封装，便于 PCB 布局与自动贴装。工作温度为商业级范围，适合一般室温环境和工业室内应用；对更苛刻环境建议选用工业级或经过温度筛选的替代品。
六、设计与使用建议
- 电源端加适当去耦电容（如 0.1 μF 与 10 μF 并联）以抑制电源噪声与瞬态。
- 对高阻抗输入使用防静电与防电荷注入措施，避免输入偏置电流带来的误差。
- 在驱动容性负载时注意稳定性，可在输出与地之间并联小电阻或在反馈回路中增加补偿。
- 依据 GBW 选取合适的闭环增益，避免带宽不足引起的幅频衰减或相位裕度下降。
LM2904 以其低功耗、宽电压支持与良好通用性，为多种模拟设计提供经济可靠的解决方案。根据应用需求合理布局与选型，可获得稳定且精确的性能表现。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
