LTC6655 - 0.25ppm 噪声、低漂移、精准基准系列

LTC®6655 是一个精准带隙电压基准的完整系列，可提供卓越的噪声和漂移性能。其低噪声和低漂移非常适合于仪表和测试设备所要求的高分辨率测量。而且，LTC6655 规格在 –40ºC 至 125ºC 温度范围，确保其适合汽车和工业应用。先进的曲率补偿功能使得该带隙基准能够实现一个少于 2ppm/ºC 的漂移和一个可预知的温度特性、以及一个达 ±0.025% 的输出电压准确度，从而降低或免除了进行校准的需要。

LTC6655 可由低至比输出电压高 500mV 的电压来供电，也可以从高达 13.2V 的电压来供电。出色的负载调节以及供应和吸收能力、再加上超卓的电压抑制性能，因而在很宽的运作范围内提供一致的性能。对于低功率应用，该器件提供了一种停机模式。

LTC6655 基准采用 8 引脚 MSOP 封装和 8 引脚 LS8 封装。LS8 是 5mm x 5mm 表面贴密封型封装，可提供卓越稳定性。
