I have an application where I need a very low noise A/D converter and I need to be able to sync it with 6 other converters so they sample at exactly the same time and at the same rate. I'm looking at the ADS1255. It has a sync input on it, but very little on how this works. Is there an app note? Or is there another converter better suited? Need 0 to 5V input range.
The datasheet says how to do this, but makes no mention of how this affects the filtering frequencies.
