Consideration for a Simple Analog Circuit

Nice depiction of the circuit. Do you have a question?

Well it's a little hard to elaborate more than I have already without knowing what the sourcing signal is or what the load is that you will be driving. Now there is one significant problem that you may have with not having a symmetric supply, all voltage swings should be referenced to above and below the mid-voltage point of your supply. The common method of doing this is by generating a virtual ground by using another operational amplifier in a voltage follower configuration with the + high input impedance input connected to the middle of two matched dropping resistors (making Vcc/2) the output connected to the negative input through a resistor one half of the previous two resistors. This op-amp output now becomes a low output impedance virtual ground. But once again, depending on what you're doing this maybe a needless effort. But I always like to go back to the original source whenever a circuit is not doing what I wish. National Semiconductor did the original design of the quad amplifier package, LM324N. Oh, and the single amplifier two pole design they show happens to be a Sallen-Key configuration.

If I remember correctly, a drawback of the Sallen-Key design is that at much higher frequencies than the -3dB corner frequency the attenuation cannot be as much as one would expect. Once again, many times this does not matter. It all depends on what you're doing.
