The question hasn't been answered, because I still don't know how to correctly build a filter to attenuate the 2Hz - 200KHz bandwidth.
I already have a schematic, but I didn't think it was necessary to post it, considering that all I needed was realistic L and C values for a multi stage filter...
Cost really isn't a real concern for me, but the size of the circuit will be. The enclosure space I have to work with for the whole device is 450x70x300mm WxHxD (approx)
To look at it from another perspective. The goal is to create a power supply that can deliver clean power between 6V and 12V...
Thanks for letting me know about that godfreyl, I can put in some ceramic capacitors, and possibly some ferrite inductors at the input of the regulator to prevent high frequencies from reaching the regulator.

The noise I am looking for, is any level of noise on any...
I have already consulted the data sheet for the DC regulator and optimized the regulator for the best performance that is possible. DC ripple is just one of the reasons for having such a wide band filter. Noise and any other unwanted signals are also a priority. The goal is to make the DC output...
I should have mentioned in my initial post.
The AC to DC supply will be linear, The multi-stage filter will be mainly to deal with DC ripple from the rectification stage, and any noise/unwanted signals within the 2Hz - 200KHz bandwidth.
I will use additional ceramic capacitors and ferrite...
Hi all
I'm new to these forums.
I am planning to build a multistage LC low pass filter for the output of an AC to DC converter.
The output of the supply will be adjustable between 6V - 12V at 2A of steady current. The required cut off frequency required for the multi-stage filter is 2Hz.
The...
I had suspected that the LTC490 would need an 8-pin dip socket, but I wasn't sure.
Thanks for your help Barry.
I had opted to use sockets to prevent heat damaging the IC during soldering, but I will just have to be careful instead.
Yes, that is the problem. I have the ICs themselves picked out, but I am not sure which socket to pick that will fit the IC.
I am having trouble finding the relevant information on the data sheet that tells me which socket would be most suitable for that IC.
Hi all
I am new to these forums.
I have recently started designing small electronics projects, at least until I gain experience then maybe I can move onto more complex circuits.
The first project I am working on is comprised mainly from ICs, and I would like to use IC sockets in the...
