So I'm contemplating building a CMOY of some sorts, but would most likely use the AD8620AR opamp I ordered about a week ago. I see it can draw up to 45mA per channel, +-30mA typical according to the DS.
I was also reading up on the virtual ground layouts using TLE2426, but they can sink around 20mA.
Then I saw the PenguinAmp ... this uses 2x TLE2426 for the virtual ground circuit. Why? How? One for each opamp in a dual package?
Yes, I'm a newb. Homework first. Soldering iron into eye later. I like a bit of safety margin so it didn't seem like the TLE2426 could pass enough current for the AD8620. As with all newbies though, I'm looking for something with the least amount of bits and pieces, yet a little up from the standard 2 resistor voltage splitter.
