Hi
I seem to recall TI having similar parts.
The big gotcha is tossing large chunks of C onto the ground to rail
connections. A typical op amp is not at all happy with this.

Yeah, but that virtual ground brings with it it's own set of problems.
For instance, it has to both sink and source current, so you can't just
use a 3 terminal regulator to create the midpoint, although I've seen
schemes with a resistor
I've ALWAYS used an op-amp to nail down the half rail supply, I never
use the two resistors and cap idea directly unless the whole thing is
quite basic
Just don't put bulk capacitance on the output !
like I have seen in some bad designs. ROFL.
Some op-amps are better at this than
