【应用】国产串联型电压基准TPR3330用于通信基站功放电路监控,实现高精度数据采样
通信基站中最体现技术水平的就是功放电路,功放电路的每一个细节,决定了通信基站的性能。采用国产品牌思瑞浦公司推出的串联型电压基准TPR3330,用于功放电路ADC采样的电压参考源,可以实现高精度数据采样,同时有助于国产化、降低成本,减少供应链风险。
ADC采样典型应用电路如下图所示。
作为电压参考,最主要的指标是电压精度、温漂和输出噪声。三者直接决定了采样准确度,TPR3330的这三个指标都有不错表现:
1、电压精度
TPR3330的输出标准值是3V,最大初始精度为±0.15%,满足绝大多数ADC采样需求。
2、温漂
除了常温精度,温漂小表明在高低温下的温度精度,TPR3330在-40~+80℃范围的温漂最大值为20ppm/℃,在-40~+125℃范围的温漂最大值为30ppm/℃,即使在5G通信基站温度比较高的情况下,也能保证输出精度。
3、输出噪声
TPR3330的输出噪声为60μVpp@(0.1~10)Hz,可以尽可能减少对ADC采样精度的影响。
另外,TPR3330输入电压为3.2~5.5V,方便接入常用的3.3或5V电压,静态工作电流180μA,不会造成额外的功率浪费,提供常用的SOT23-3封装和小尺寸1.5x1.5mm的QFN封装,如下图,满足不同设计需求。
作为国内模拟芯片领军企业,思瑞浦在技术支持、产品质量、供应保障等方面,得到客户一直好评,国产产品一般在成本上也具备优势。所以,采用TPR3330应用于ADC采样电路中,可以满足提高性能、国产化、降本、改善供应链的需求,应为设计优选。

【选型】通信基站上国产电压基准源TPR431B-S3TR可PTP兼容TI的TL431BQDBZR
通信基站项目中,0.5%精度的2.5V电压基准源,许多设计原先采用TL431BQDBZR,在目前芯片短缺形势下,为了预防采购问题导致的生产难题,需要做国产化设计。本文对TI的TL431BQDBZR和3PEAK(思瑞浦)的TPR431B-S3TR做一个参数对比,为设计者提供参考。
