  2. 放大器组数: 2（双路通道设计）
  3. 运放类型: 通用运算放大器
  4. 功耗: 各通道功耗为 700 µA
  5. 压摆率 (SR): 0.6 V/µs
  6. 工作温度范围: -40°C 至 105°C
  7. 电源电压范围: 3V 到 30V, 或 ±1.5V 到 ±15V
  8. 输入特性:
    • 输入偏置电流: 20 nA
    • 输入补偿电压: 1 mV
  9. 输出特性: 每通道输出电流可达 60 mA
  10. 封装: 8-SOIC（0.154" 或 3.90 mm 宽）
  11. 安装类型: 表面贴装型 (SMD)

三、性能特征

LM258DT 的增益带宽积 (GBP) 为 1.1 MHz，体现了其在信号处理中的高频性能，能够处理高频信号的放大需求。压摆率 (SR) 为 0.6 V/µs，使其在快速变化的信号中提供稳定性和可靠性，适合用于对速度有一定要求的应用场合。

其低输入偏置电流 (20 nA) 和输入补偿电压 (1 mV) 使得 LM258DT 在高精度信号放大时表现出色，特别是在传感器接口和高速数据采集系统中。此外，该器件的输入和输出电流能力（输出电流可达60 mA）为驱动后续的电路提供了保障，能够适应较为复杂的设备负载。

四、应用领域

由于其广泛的工作电压范围和可靠的温度特性，LM258DT 可在各种极端环境条件下正常工作，适用于如下应用：

  1. 工业自动化: 适用于传感器信号放大和实时数据采集。
  2. 消费电子: 可用在音频设备、视频处理器等领域，提供高精度信号处理。
  3. 汽车电子: 在车载系统中可作为传感器放大器、信号调节器等。
  4. 医疗设备: 作为生物信号处理，例如心电图 (ECG) 监测系统。
  5. 无线通信: 用于调制解调器、放大器和其他 RF 应用。

五、总结

LM258DT 是一款表现出色的双路通用运算放大器，凭借其优越的性能参数和广泛的应用潜力，深入到现代电子电路设计中。无论在极端的温度环境下，还是在对功耗严格控制的设计中，LM258DT 均展现出其独特的优势，成为许多工程师的首选器件。在设计新一代电子产品时，LM258DT 以其高集成度和可靠性，为实现高效、稳定的电路功能提供了强有力的支持。

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
