LT6656 - 1μA 精准串联电压基准

LT®6656 是一款小型精准电压基准，所吸收的电源电流小于 1μA，并能够采用一个位于输出电压的 10mV 以内之工作电源电压。LT6656 提供了一个 0.05% 的初始准确度和 10ppm/ºC 的温度漂移。由于兼具低功率和精准特性，因此该器件非常适合于便携式和电池供电型仪表。

LT6656 能够提供高达 5mA 的输出驱动电流和 65ppm/mA 的负载调整率，从而使其可被用作一个低功率 ADC 的电源电压和基准输入。LT6656 可接受一个高达 18V 的电源电压，并安全地承受输入反接。

LT6656 的输出能够在采用 1μF 或更大的输出电容时保持稳定，并可在多种输出电容器 ESR 条件下运作。

该基准的技术规格针对 –40ºC 至 85ºC 的工作温度范围，并能够在 -55ºC 至 125ºC 的极限温度范围内运行。通过运用先进的设计、工艺和封装技术实现了低迟滞和一致的温度漂移。

LT6656 可提供 6 引脚 SOT-23、(2mm x 2mm) DFN 和8 引脚 LS8 封装。LS8 是一个5mm x 5mm 表面贴装密封式封装，能提供卓越的稳定性。
