The maximum power supply voltage for the TL084MFKB is ±18V, or 36V total.
While the TL084MFKB has a high gain-bandwidth product, its unity-gain bandwidth is around 3MHz, making it more suitable for low- to medium-frequency applications.
Yes, the TL084MFKB can be used in a single-supply configuration, but the input common-mode voltage range is limited, and the output voltage swing may be reduced.
To ensure stability, use a compensation capacitor between the output and the inverting input, and consider adding a series resistor to the feedback path to reduce oscillations.
While the TL084MFKB has a relatively low noise floor, its distortion performance may not be suitable for high-fidelity audio applications. Consider using a more specialized audio op-amp instead.
