3 说明

LM4040-N 精密电压基准非常适合空间关键型 应用，可采用小型 SC70 和 SOT-23 表面贴装封装。LM4040-N 采用了先进的设计，无需使用外部稳定电容器，同时可确保任何容性负载下的稳定性，这使得 LM4040-N 非常易于使用。它还提供了 2.048V、2.5V、3V、4.096V、5V、8.192V 和 10V 的固定反向击穿电压，可帮助设计人员进一步减少设计工作。最低运行电流范围为 60μA (2.5V LM4040-N) 至 100μA (10V LM4040-N)。所有版本都具有 15mA 的最高运行电流。

LM4040-N 在晶圆筛选期间使用了保险丝和齐纳击穿反向击穿电压修整，以确保主要部件在 25°C 下的精度优于 ±0.1%（A 级）。带隙基准温漂曲率校正和低动态阻抗可确保在广泛的运行温度和电流范围内实现稳定的反向击穿电压精度。

此外，我们还提供了具有两个反向击穿电压版本的 LM4041-N：可调节电压版和 1.2V 版。请参阅 LM4041-N 产品说明书 (SNOS641)。
