operational amplifier - how to split audio with buffers ...
https://electronics.stackexchange.com/questions/197827/how-to-split-audio-with-buffers
This is a typical powered headphone splitter/amplifier. It is a single gain amp to multiple non-amplifying buffers. The 5.1kΩ Resistors represent the load. As it will be in parallel with your actual load, they won't affect much. Notice, no pull-down resistors needed between the Gain Amp and Buffer Amps. This is as generic as it gets.

simple buffer/splitter for audio lines with op amp. I have to realize a simple circuit to split the line OUT from a sound card PC (green jack 3.5mm) People normally uses a Y-cable as splitter, but unfortunately it introduces some attenuation and. noise. The power supply is provided by a standard USB port, so the voltage is 5 V±5% and.

Figure 2. Schematic Diagram of Small Audio Power Amplifier Circuit Using Op-Amp and Two Transistors. Let’s imagine the op-amp is omitted, then the base-to-base voltage is the voltage between R4 and R5 which is dropped by two diodes D1-D2. This voltage is slightly higher than base-to-base bias requirement to produce small leakage current when ...

I have been experimenting with op-amp audio amplifiers powered from a 9V battery. I am just wondering how I should go about splitting the voltage from the battery, as I have found 2 ways of doing this . . . CIRCUIT 1: One method is to make the ground rail the -ve terminal of the battery and then DC offset the input signal . . . CIRCUIT 2:

An op-amp can be used as a non-inverting DC amplifier with offset compensation by using the connections shown in Figure 3, which shows an x10 amplifier. The voltage gain is determined by the ratios of R1 and R2, as indicated. If R1 is given a value of zero, the gain falls to unity; alternatively, if R2 is given a value of zero, the gain equals ...

op amp. In the circuits in the figures that follow, the virtual ground is labeled “VCC/2.” This voltage comes from either the TLE2426 rail-splitter or the circuit in Figure 1. If the latter is used, the overall number of op amps in the design is increased by one. Passive components The majority of the circuits given in this series have been
