【选型】国产低温漂电源基准SGM4029-2.5XS8G/TR助力雷达系统采集板，噪声低至3.4μVP-P/V
客户在雷达系统采集控制单元，原使用国际主流品牌的电源基准源，由于项目国产化需求，笔者结合应用为其推荐SGMICRO推出的SGM4029-2.5XS8G/TR，是一款具有极低噪声和漂移的精密电压基准。应用于电路中，在输出引脚处具有汇聚吸收电流的能力，可帮助系统提升带载和线路调节能力。
SGM4029-2.5XS8G/TR的典型应用电路基本如下：
SGM4029-2.5XS8G/TR应用于产品中会带来如下优势：
1、基准电压偏差小。初始精度典型值为±0.05%，最大在±0.1%内，可保证初始精度准确。
2、工作范围内漂移小。在工作温度为0℃至+85℃，典型温漂为3ppm/℃，在工作温度为-40℃至+125℃时，典型温漂为5ppm/℃，可满足大部分应用需求。
3、干扰小。具有极低噪声，在0.1Hz~10Hz频率范围时只有3.4μVp-p/V的超低噪声，可以降低系统干扰，提高产品的稳定性。
4、带载能力高。输出电流高达±10mA，带载能力强，可适应大部分应用。
5、兼容度高，采用市面主流的SOIC-8封装，可较好的兼容同类产品，方便客户做兼容设计。
综上所述，低温漂电源基准SGM4029-2.5XS8G/TR以其低温漂、高精度及超低的噪声参数等性能优势可满足客户在雷达系统采集单元的方案设计要求，兼容度高，应用极其简单可尽快实现方案国产化。作为国产品牌，在价格、交期及技术支持上均有一定的优势。
