You're right... I guess I had a brain fart, I don't know where my mind was at that moment... ;) Anyhow, besides using a buffer chip (like the several mentioned in other posts), how would using a plain old voltage following op-amp compare? I haven't looked up any specs yet, I'm just throwing the idea out there. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
