How long does it take for our customers to complete an AD conversion using the 24-bit analog sampling function of msp430afe253? Fixed? How does it calculate? When reading data, a total of 24 bits can only read high 16BIT (sD24LSBACC = 0), then set D24LSBACC to 1, and then read low 16BIT. Is that right?
Hi elan,
The 24-bit ADC value reading method you described is correct. You can also refer to this post:

For the SD24 sampling rate problem, you can refer to this post:
Some code example maybe useful for you :
