TL082CDR datasheet by Texas Instruments

TL082CDR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL082CDR?
  The maximum power dissipation of the TL082CDR 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 TL082CDR in a high-temperature environment?
  While the TL082CDR is rated for operation up to 125°C, its performance may degrade at high temperatures. It's recommended to derate the power dissipation and ensure proper heat sinking to maintain reliability.
• How do I ensure stability in my TL082CDR-based circuit?
  To ensure stability, ensure that the circuit is properly compensated, and the gain-bandwidth product is not exceeded. Also, use a bypass capacitor (e.g., 10nF) between the power supply pins to reduce noise and oscillations.
• What is the recommended layout and routing for the TL082CDR?
  Keep the input and output traces short and separate, and avoid running them parallel to each other. Use a ground plane and decouple the power supply pins with capacitors (e.g., 10uF and 100nF) to reduce noise and oscillations.
• Can I use the TL082CDR as a comparator?
  While the TL082CDR can be used as a comparator, it's not the best choice due to its relatively slow slew rate (13V/us) and limited output current (±20mA). Consider using a dedicated comparator IC for better performance.
