Hi Miguel,
Thanks again, but maybe I wasn't clear. I know how to read the schematics and make the connections. My question is regarding the DC-DC converters I must use in order to get isolation from USB power to the analog and digital part of the ADS1298/1299. I was even considering desing my own converter with external transformer and couple of drivers, but, since is a low power circuit (50mA maybe more), I thought I could find a simplier solution, maybe one IC with isolated DC-DC converter and isolated digital transciever (I found one of those from another manufacturer but the output power was only 10mW and the isolated part of my device may require more). I would appreciate any specific ideas.
Best regards,
Juan Manuel
