AFE5808: Noise question of AFE5808

Part Number: AFE5808

HI team,

Here is FAE in south China, my customer has some concern on the noise of CW doppler:

for input voltage noise, 1 channel is 0.8 while 8 channel is 0.33? why 8 channles has lower noise than 1 channel?

the same thing happened on output voltage noise, 1 channel is 12 while 8 channles is 5?

do you have some comments on this question?

thanks very much.

Regards, Sunny.

    Hi Sunny,

    This is likely due to the averaging effect on the noise when multiple CW channels are summed together.

    Sincerely,

    Olu
