What is a buffering circuit?
https://www3.nd.edu/~lemmon/courses/ee224/web-manual/web-manual/lab5/node6.html
A buffer is a unity-gain amplifier that has an extremely high input resistance and an extremely low output resistance. This means that the buffer can be modelled as a voltage controlled voltage source that has a gain of one. We connect the buffer to our DAC as shown in figure 6. Note that we've represented the DAC by its Thevenin equivalent circuit.

Amplifier Circuits Introduction to Impedance and Bandwidth Control. Modified Response Curves Previous modules have concentrated on producing a flat frequency response over the required audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency

The circuit shown has a gain of 11.2, and if the Figure 4 circuit were used, the input resistor (R1) would have to be 10k, and feedback resistor (R2) would then be 112k (gain is R2/R1). The high value feedback resistor creates noise (see Noise In Audio Amplifiers for details). By using the arrangement shown, resistor values are reduced and so ...
