意法半导体’的精密并联电压参考包括:

  • 大功率参考,最高阴极电流为100 mA
  • 可调输出电压:0.6~36 V
  • 微功率参考,专门面向便携式应用,最低阴极电流低至40 µA,精度高达0.1%

它们的功能与齐纳二极管相似,但是技术规格更高。

LM4041 micropower shunt voltage reference

Demonstrating a stable 1.225 V output voltage at very high precision with an initial accuracy of 0.1% @ 25 °C, the LM4041 shunt voltage reference exhibits an ultra-low operating current of 40 μA which makes it ideal for micropower designs. It is available in the low noise and small SOT323-5L and SOT23-3L surface mount packages.
