According the datasheet of the DAC11001A, the spectral noise density is 7nV/sqrt(Hz). And the LF noise from 0.1Hz to 10Hz is specified with 0.4uVpp.

Hi All,
I want to design a WiFi operated Smart LED Bulb with Standard AC input and Also need to control dimming via micro controller as well as will drive WiFi module also.
Can anyone suggest me any solution for these requirement.
Can you suggest me IC…

I’ve calculated the noise of a circuit based on OPA354 and I find out that the calculation doesn’t match with the simulation. I try to build…
Hello David,
The PGA280 is has the zero-drift feature with provides low-offset, low-drift and no 1/f noise. The input referred noise spectrum plot, in figure 15 of the datasheet, shows no 1/f at the frequency region of interest 0.1Hz- 10Hz. I have posted th…
Hi Jose,
Thanks for your reply, I have read it with a lot of interest. However, I did some experiments that still raise some new questions. Please have a look at the attached pdf and let me know what you think.
Best regards,

The 1/f (one-over-f) low frequency noise region of amplifiers seems just a bit mysterious. Reader “tweet” asked for a discussion of 1/f noise—a challenging topic for a short blog.

The LMC6442 is a very attractive amplifier for my application due it's very low Ib and drift, however low frequency (<0.1-10Hz) noise is also very important for me and I can't find a figure for it. Extending the…
Mujahid;
There are a number of things that can cause the output to be influenced by the ambient air-- as you said "Air Con Off". One is simply the thermoelectric potentials caused by dissimilar metals in the input portion of your circuit. Very high gain…
