In D/S, a condition of current noise density is 100kHz.
Our customer needs a current noise density of AD8034 at "1kHz".
Can you provide this spec or the data that corner frequency can be decided?
I already contacted the product owner regarding this. I will get back to you as soon as I have the information.
I am waiting for your reply.
Current noise is flat to lower frequency (below 1kHz). This is same as the voltage noise. May I know what value of the feedback resistor you're using?
Sorry for the late reply.
I am getting confirmation from the customer now.
Our customer is using 2k、200k、20M of feed back resister.
But, as far as I know the voltage noise is not flat to lower frequency.
Could you answer this question?
FET input amplifiers don't have 1/f current noise. The voltage noise will increase at lower frequencies but the current noise will not.
