Other Parts Discussed in Thread: AFE4400

Hi,

I would like to ask you a question about AFE4400 as below.

Q) the A/D data number for avaraging

AFE4400 does "data avaraging" to remove external noise after A/D every 50uSec.

The A/D data which are used to avarage seems to be fixed unmber.

How do you fix the number? Is it determined by PRF (Pulse Repetition Frequency)?

Thank you for your support.

Best Regards,

Hi Takumi,

The Control1 register has Bit 1 fixed to 1.

Please refer to Figure 89 on page 62 in the following datasheet for the register table.

Best Regards,

Hi Lakeishia-san,

Thank you for your reply.

Let me confirm your answer.

Do you mean that "Bit1=1" means "average number" is "2" data?
