Section 1 --
Introduction:

"Split Supply" Op AMPs run off a center-tapped transformer with a common point normally as output. The advantage of split supply to op-amps is to reduce the size of the output DC filter capacitor. Single supply is where common point is the op amp's supply point ether negative or positive. Split supply allows the op amp to amplify Negative portions of a signal as well as the positive. Regular single supplies will ride the AC signal on a DC level when amplified but the DC will need to be filtered via filter capacitor.
