REF35超低功耗高精度电压基准是毫微功耗、低漂移、高精度参考器件，初始精度高达±0.05%，功耗通常低于700nA,低温漂移 (10ppm/°C) 和长期漂移（20ppm，1000小时）确保系统稳定性和可靠性。REF35元件具有低功耗和高精度规格，因此可用于各种便携式和低电流应用。REF35超低功耗精密电压基准的工作温度范围为-40°C至+125°C，在-55°C至+125°C宽温度范围内可以正常工作，因此适合用于工业应用。
|
|
REF35提供高达10mA电流，具有8.5ppmp-p噪声和30ppm/mA负载调节能力,凭借这些特性，REF35可为精密传感器和12-16b数据转换器提供强大的低噪声、高精度电源且具有1.024V至5.0V宽输出电压范围，采用节省空间的SOT23 6引脚封装。
