As usual I discover something new every time I search these forums. I started my Pimeta build. Took a break and began searching here for info on the Jung Multi loop circuit and gain in the Pimeta. What I found was more questions.
While preparing and ordering parts I ran across a spreadsheet with Resistor values for adjusting gain based on opamp and bandwidth, I thought in the Pimeta.
Then I ran into these threads:
MINT gain vs. bandwidth question
Post #9 and 10
Pimeta gain
These are the values I have now.
opamp - AD8620
R3, R5 - .357K
R4 - various Gain adjust
R6 825K
Based on these thread discussions I'm thinking I need to reorder all my resistors for the R3 through R6 so they match the schematic values and make my gain adustments with R4 only.
Am I correct or will the spreadsheet resistor configuration I have work?
On the bright side I have socketed about everything.
Thanks
