trouble with biasing rev 3.6
Posted: Tue May 25, 2010 5:15 pm
Hi,
I'm trying to do the last few steps to adjust the input bias current, and i'm not 100% sure I have it right.
At steps 42+44 I am only getting a dcv reading of 0 on each extreme of the SW1 without adjusting R43. Is this correct?
I am using the AD797 opamps and I have sockets mounted to the pcb and then the 797 placed in the socket.
Any ideas? or am I good so far.
thanks
kris
