dc servo in preamp
hi guys
just interested in your collective opinion. i'm using lm4780s'. I plan to add an opamp buffer and pot before this chip. would it be worth adding a dc servo to the opamp input.. (as a learning exercise really) dc offset on the lm4780s is 16mv and 18mv |

Does your LM4780 work as AC or DC coupled?
And if youre mentioning about a buffer works in unity gain (it must be, if its a real buffer) then how you will apply a DC servo to it? I havent seen any DC servo application with unity gain stages!
