Hi all,
I have a sensor that outputs 0-4V for a 0-5A current flow. It is being powered by a bench power supply with +/- 15V. The output from the sensor appears very noist at 50mV pk-pk. This noise is present throughout it's range. Is there a simple filter design that I could utilise to at least reduce the noise by 70%?
Thanks in advance! 
What are you using this for?
Hi,
How do you know the noise is not on the current you are monitoring.
By the way for all, the sensor is; (lets not keep it a secret)
An AC/DC Hall Effect Current Clamp.
Tom.. 
General purpose measurement of current from 0-5A.
With no current flowing through the sensor there is still noise present around above and below the 0V region so I know it's not the source creating it.
Connect oscilloscope and show as the noise, I think that is not a noise.
The data sheet says Noise level = 20mV p-p so if it's 15mV you are lucky
The noise is around 50mV not 15mV so unlucky I think 
That is a noise + hum, use RC filter 10k, 1uF.

Just tried 510R and 10uF and it has reduced to 30mV pk-pk which is a good improvement, thanks for your help!
