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

Any amplifier can be run on a single supply. Op amps don't have a ground pin and are equally happy when run on a bipolar supply as they are with a single supply. Additional bias circuitry is required when running an amplifier in this configuration, however. As a result, the amplifier's performance may suffer slightly in the following areas: lower bandwidth, degraded power …

Any op-amp can be configured to work as an audio amplifier running from a single supply. The issue is the minimum supply voltage it needs to work from. The TL072 is specified to work down to 4.5V and the NE5532 down to 6V but whether it'll actually work depends on how it's configured and the requirements for the design. Please post a schematic.

I am currently designing an audio amplifier using the LM324. I am operating from a single supply of 9 V. Here is the schematic: Here are the design steps I took: I needed a gain of 100 so G = 1+(100/1) = 101. The input capacitor C1 forms a high pass filter with R1||R2.

standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V with quiescent currents about one−fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the

LM358 op-amp, which is a low-power device that can be operated from a single voltage supply, therefore appropriate for battery-operated circuits. Low-power op-amps draw very little quiescent current and hence help prolong the life of the battery. The LM358 is a garden-variety op-amp and there are many other possibilities that could be used, but this one is very cheap!
