LT1461 - 微功率、精准、低压差、串联电压基准系列
LT®1461 是一个低压差微功率带隙基准系列，它兼具非常高的准确度和低漂移、以及低电源电流和高输出驱动。这些串联基准采用了先进的曲率补偿方法 (以获得低温度系数) 和经修整的精准薄膜电阻器 (用于实现高输出准确度)。LT1461 系列仅吸收 35μA 的电源电流，因而使其成为低功率和便携式应用的理想选择；然而，其 50mA 的高输出驱动电流则使其很适合于较高的功率要求，例如：精准稳压器。
在低功率应用中，一个 <300mV 的低压差电压可确保最大的电池寿命，同时保持完整的基准性能。电压调整率几乎是不能测量的，而非常优越的负载和热调整性能将不会导致系统误差预算的显著增加。停机功能可用于满负载电流的开关操作以及系统断电。热停机功能可保护器件免遭过载情况的损坏。LT1461 可提供 2.5V、3V、3.3V、4.096V 和 5V 选项。
