Application Scenarios & Design Considerations

Quad JFET-Input General-Purpose Operational Amplifier

Alternative Part Number

  • LM324DR --: Quad general-purpose op-amp in SOIC-14, widely available and pin-compatible in most circuits, though lower bandwidth than TL084.
  • MC33079DR2G --: Quad low-noise op-amp in SOIC-14 with similar supply range and pinout, suitable drop-in for many TL084 applications.
  • OPA4134UA --: Quad audio-grade op-amp in SOIC-14 offering improved performance over TL084, pin-compatible with the same footprint.
  • LF347N --: Quad JFET-input op-amp with similar bandwidth and input characteristics, widely used as a direct substitute in TL08x sockets.
  • MC34004P --: Quad bipolar/JFET op-amp pin-compatible with TL084, offering comparable supply range and performance for general-purpose applications.
