ADS1263 32位ADC 评估板文件 [复制链接]

 

画了一块ADS1263的评估板
使用4层板（实际可改为2层）
支持电阻、电压、电流测量
电压测量使用CADDOCK 1776-C681分压电阻网络

支持1：10、1：100、1：1000、1：10000分压
支持1200V输入
分压精度0.05%
5ppm温漂

板子使用Arduino通用接口
使用CC2541做了简单测试

通过手机查看测试数据


短接VIN+和VIN-时测试数据




使用LTC6655 4.096基准，通过750ohm*2 5%电阻分压后测量的数据
ADS1263在GAIN=1 2.5SPS时的噪声为1uV以内
LTC6655的噪声也在1uV以内
而实际测量时的噪声是12uV左右
因为手里没有台式万用表
还不能确定噪声是LTC6655评估板出来的
还是ADS1263评估板产生的

有了解的网友麻烦帮我分析一下



调换输入极性

数据图表是软件滤波以后的数据吗？有没有原始数据？

是原始数据 曲线做平滑处理了
