请问:ADS1147 是否支持热电偶测温,热电阻测冷端温度的问题,我看数据手册中 只有讲到ADS1148/1248 有这种方案,不知道ADS1147是否可以?产生这个疑问的原因,是看官方提供的一篇技术文章:SBAA180B-Example Temperature Measurement Applications Using the ADS1247 and ADS1248 中figure 4 典型应用中标明,ADS1247/1248 可以这样应用,所以不知道ADS1147是否可以?谢谢!!

可以的,在datasheet Page1 就有介绍ADS1147的特性,然后说明了应用:
These features provide a complete front-end solution for temperature sensor measurement applications including thermocouples, thermistors, and resistance temperature detectors (RTDs) and other small signal measurements including resistive bridge sensors.
