single supply testing. -I have purchased a single supply opamp TLC084 and tested it with a wave generator up to 20khz no problems @ 200mvpp and unity gain no problems. -When i use the same circuit and instead of inputing the wave i input the audio signal ~200mvpp. The audio is only amplified in for very small periods and sounds noisy and poppy ...

The single-supply op amp design is more complicated than a spilt- or dual-supply op amp, but single-supply op amps are more popular because of their portability. New op amps, such as the TLC247X, TLC07X, and TLC08X have excellent single-supply parameters. When used in the correct applications, these op amps yield

a single 30V power supply. The op amp still has a total of 30V across the power supply terminals, but in this case it comes from a single positive supply. Operation is otherwise unchanged. The output is capable of following the input as long as the input comes no closer than 2V from either supply terminal of the op amp. The usable range of the circuit

Why is a single supply voltage is seldom used for audio mixers”. Because in audio circuits the circuits become much simpler when used with a symmetric supply voltage (like +/- 15V). If one were to use a single 30 V supply (for example) then you have to take measures to DC bias the inputs of the opamps to a voltage somewhere "in the middle", with a 30 V supply that …
