TI的技术员您好:
请问ADS1298但 单步转换 的最高速率能达到多少?我现在做了实验,单步转换能达100SPS再高就不行了,不知道为什么?请给指点,谢谢

datasheet中有提到,Single-shot conversion mode is provided for applications that require nonstandard or noncontinuous data rates. Issue a START command or toggle the START pin high to reset the digital filter, effectively dropping the data rate by a factor of four. 也就是说,如果当前您设置的data rate为500sps的话,single shot 模式,输出data rate为500/4=125sps. 所以您可以检查下配置寄存器DR的设置,设置的output data rate为多少。
