TL084ACN Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL084ACN?
  The maximum power dissipation of the TL084ACN is 670mW, which is calculated based on the maximum junction temperature (150°C) and the thermal resistance (RθJA) of 100°C/W.
• Can I use the TL084ACN in a high-temperature environment?
  While the TL084ACN is rated for operation up to 125°C, it's not recommended to use it in high-temperature environments above 85°C without proper heat sinking and thermal management, as this can affect its reliability and lifespan.
• How do I ensure stability when using the TL084ACN in a feedback loop?
  To ensure stability, make sure to follow proper compensation techniques, such as adding a capacitor in the feedback loop or using a resistor in series with the capacitor to prevent oscillations. Also, ensure that the gain-bandwidth product is not exceeded.
• What is the recommended layout and PCB design for the TL084ACN?
  For optimal performance, use a symmetrical layout, keep the input and output traces short and away from noise sources, and use a solid ground plane. Also, decouple the power supply with a 10uF capacitor and a 100nF capacitor in parallel.
• Can I use the TL084ACN as a comparator?
  While the TL084ACN can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (0.5V/us) and limited bandwidth (3MHz). A dedicated comparator like the LM339 or LM393 would be a better choice for most applications.
