TL084CD datasheet by Texas Instruments

TL084CD Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL084CD?
  The maximum power dissipation of the TL084CD is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (RθJA) of 125°C/W.
• Can I use the TL084CD as a comparator?
  While the TL084CD can be used as a comparator, it's not the best choice due to its relatively slow slew rate (13V/μs) and limited bandwidth (3MHz). A dedicated comparator like the LM339 or LM2901 would be a better option.
• How do I ensure stability when using the TL084CD in a unity-gain buffer configuration?
  To ensure stability in a unity-gain buffer configuration, make sure to add a capacitor (typically 10-100nF) between the output and the inverting input to prevent oscillations. Additionally, use a low-ESR capacitor (e.g., ceramic or film capacitor) to minimize phase shift.
• What is the recommended layout and routing for the TL084CD?
  To minimize noise and ensure proper operation, keep the input traces short and away from the output traces. Use a ground plane and decouple the power supply with a 10uF capacitor. Route the output traces away from the input traces and avoid running them parallel to each other.
• Can I use the TL084CD in a high-temperature environment?
  The TL084CD is rated for operation up to 125°C, but its performance may degrade at high temperatures. If you need to operate the device in a high-temperature environment, consider using a more temperature-stable op-amp like the OPAx317 or OPAx227.
