Application Scenarios & Design Considerations

Quad JFET-Input General-Purpose Operational Amplifier

Alternative Part Number

  • LM324DR --: Quad operational amplifier in SOIC-8, widely available and pin-compatible in most circuits, though it has lower bandwidth and is a good low-cost substitute for non-critical applications.
  • MC33079DR2G --: Quad bipolar op-amp in SOIC-8 with similar JFET-like input characteristics and supply range, suitable as a functional replacement in many TL084 applications.
  • LF347DR --: Quad JFET-input operational amplifier in SOIC-8 with very similar input bias current and bandwidth specifications, making it a close electrical match to the TL084.
