Re: Need Amp. Very Low Zout

if u connect a amp as a negative feedback configuration, then the output of amp is Zout=Rout/(1+Aβ) ,where Rout is the output resistance of amp in a open loop.
Zout=<1, u can select an amp with Rout=1k ohm, and connect it to be a voltage follower (β=1), and the amp has a open-loop gain 60dB, then u will get Zout=1 ohm
