I want to use a TPA6111A2 with a split supply.   As you may know, it's pin-for-pin compatible with the old Nat'l LM4881. It's designed to be used with a single 5V supply - along with output capacitors.   Why I like this old chip is that it can easily drive 16 ohm loads - even small 8...

  Virtual Ground Circuits from Voltage Regulators     These circuits enable a two conductor DC power supply, DC wall adapter, or a battery to function as a split supply with a three conductor output (i.e., positive, negative AND ground). This sort of circuit is called a "Virtual Ground"...
