Low pass filter ic? possibly a suggestion on what's to do better

Hi, 

We'll contact the apps engineer specializing in filters and get back to you. May I know in what application will you use this? All the best!

I have three inverters that I want to measure the power consumption of; it's in a noisy environment. I will be using a microcontroller that measures voltage across 226ohm. Before measuring the voltage, I would like to remove any AC noise on the voltage signal.

Hi Shurp, 

There are a couple of low pass filters that ADI supports. Frequency is one of the considerations in selecting a filter. Would you know the frequency of operation?

Hey, I will be measuring a DC signal; therefore, low pass filter with a cutoff frequency of 20Hz, or anywhere near to DC signal would be nice. I will be using a single supply 5V, and the input voltage would be between 0.5V to 4.8V. I will constantly be measuring the DC signal coming from the current sensor. So, a small time constant filter is needed.

I have already bought LTC1063, and I will be using LTC1063 instead of LTC1062. I will test it and see where it goes. Thank you
