Questions tagged [single-supply-op-amp]

For questions about op amps that are marketed as capable of "single supply" operation. While all op amps can be operated with a single supply, op amps that are marketed as capable of "single supply" operation typically include an input common mode range and output voltage swing down to the negative supply voltage. Always use with the "operational-amplifier" tag.

For questions about op amps that are marketed as capable of "single supply" operation. While all op amps can be operated with a single supply, op amps that are marketed as capable of "single supply" operation typically include an input common mode range and output voltage swing down to the negative supply voltage. This allows the op amp to be powered with a single supply connected to its power pins, with the negative supply terminal connected to signal ground.

Always use with .

Single supply inverting op amp output

How does the output (say, a sine wave) of a single supply inverting op amp compare with output of a single supply non-inverting, since it cannot go below 0v? Is the phase shifted? I'm trying to understand what happens, since I don't have access to…

Bluetooth audio amplification

I made a circuit that consists of an operational amplifier and some capacitors and transistors so I can amplify the coming signal from any voice. Now I want to make this signal come from a Bluetooth module. How should make this connection? simply I…

Single Supply Op Amp, (With AC?)

Hey guys, I'm trying to understand how to use op amps, right now I just have a battery hooked up to the non-inverting, and a virtual ground, this is a single supply cause I don't have many tools to make split supply. The all the resistors are 220…

op amp single supply with nonlinear gain below 1 and start offset

Is it possible to create a circuit with an op amp (single supply) that have a nonlinear gain (below 1) slope and a start offset? See image Green = input Red = output

Can I bias this circuit to zero

H i, I am new to this, so please excuse my lack of knowledge. How can I bias this to zero, and is there a way to increase the dynamic range. I will mbe using this as a sound trigger for an arduino based unit. edit: What I meant by Bias to zero was.…

Can i use TL082 in a single supply configuration without any problems?

I am trying to use this op amp to work with single supply, I know that it is more recommended to go on with a near rail to rail option such as LM324 but I cannot take that route. I've tried to make a simulation on Proteus in its single supply…

Buffer OpAmp hitting high rail

I am using an STMicro TL084 Opamp in a buffer format and wondering why i keep hitting the Open Circuit +12V voltage rail. There are 2 possible connections in the below image, the first being the external 12V connector that has a 4-20mA signal. This…
