规格书上说TMS320F280049C的ADC管脚有24个，但实际好几个都是共用的。有没有24个ADC脚完全各自独立的DSP？

您好，100引脚的280034拥有27个独立的ADC引脚：https://www.ti.com.cn/product/cn/TMS320F280034

规格书写23个，100引脚的

实际上是有25个的，因为有两个引脚属于不同的Analog Group，所以之前多数了两个，不好意思。

规格书上说的23个，应该是因为有两个引脚与GPIO复用，不是单独的模拟引脚，所以他没有算。

看一下是否可以满足您的需求

B5、B11这两个口既可以模拟信号，又可以数字信号，只要内部设置就可以当模拟信号使用，是吗

另外，发现30也是B5

there are dedicated pins for B5 (pin 32) and B11 (pin 30) which respectively also
have AIO252 and AIO251 functionality. In addition, GPIO20 (pin 48) and GPIO21 (pin 49) are also available as
B5 and B11 respectively. Since B5 and B11 are dedicated pins on this package, it is recommended to use them
instead of the ones on GPIO20/21.
