LT1236 高精度基准
LT®1236 是一款高精度基准，它把超低漂移和噪声与卓越的长期稳定性和高输出准确度结合在一起。基准输出将供应和吸收高达 10mA 的电流，而且几乎完全不受输入电压变化的影响。可提供两种电压：5V 和 10V。10V 版本可用作一个并联稳压器 (两端齐纳)，具有与三端连接相同的精准特性。采取了特殊的谨慎措施以最大限度地降低热调节效应以及由温度引起的迟滞。
LT1236 兼具绝佳的准确度和温度系数指标，且并未使用高功率的片内加热器。LT1236 基准基于掩埋式齐纳二极管结构，因而消除了表面击穿器件所存在的噪声和稳定性问题。此外，即使与最好的带隙基准相比，亚表面齐纳二极管基准的温度漂移及时间稳定性指标也要更胜一筹。
