Single supply op-amp audio amplifier. Ask Question Asked 6 years, 11 months ago. Active 2 years, 1 month ago. Viewed 24k times 21 25 \$\begingroup\$ I am trying to create an op-amp amplifier that would work from single 5V supply, and would be able to amplify -100mV to +100mV audio signal to around a 1V peak-peak or so. I've came across this ...

lower voltages becoming common. Because of this, single-supply op amps are often rail-to-rail devices, which avoids losing dynamic range. Rail-to-rail may or may not apply to both the input and output stages. Be aware that even though a device might be specified as rail-to-rail, some

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

Single-Supply Op Amp Design Techniques Ron Mancini ABSTRACT This application report describes single-supply op amp applications, their portability and their design techniques. 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.

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.

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 …

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.
