3 verified alternatives for TL072
| Alternative | Manufacturer | Relationship | Key differences | Source |
|---|---|---|---|---|
| TL082 | Texas Instruments | Pin-to-pinDrop-in: same footprint and pinout. | 同系列 JFET 双运放，引脚完全兼容；失调电压与噪声指标略逊于 TL072，带宽同为 3–4MHz；音频等对噪声敏感场景需评估。 | TI TL082-N 数据手册（SNOSBW5C）的第三方镜像 |
| LF353 | Texas Instruments | Pin-to-pinDrop-in: same footprint and pinout. | 宽带 JFET 双运放，引脚兼容，压摆率 13V/µs；供电 7–36V 总电压，静态电流略高；噪声与失调与 TL072 接近，可做直接替换但需核对供电。 | TI LF353 数据手册的第三方镜像（octopart） |
| NE5532 | Texas Instruments | FunctionalSame function: board or design change needed. | 双极型低噪声音频运放，8 引脚布局相同但输入为双极型（输入阻抗低、偏置电流大），静态电流约 8mA/通道；仅适合低阻抗音频信号链，不适合 TL072 的高阻抗 JFET 输入场景。 | TI 官方数据手册 |
Pre-replacement checklist
- 确认封装（PDIP-8/SOIC-8）一致
- JFET 输入 vs 双极输入：高阻抗信号源必须用 JFET 型
- 核对供电电压范围与输出摆幅
- 音频场景核对噪声密度与失真指标
