TL082IDRG4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL082IDRG4?
  The maximum power dissipation of the TL082IDRG4 is 670mW, which is calculated based on the maximum junction temperature (150°C) and the thermal resistance from junction to ambient (θJA) of 125°C/W.
• Can I use the TL082IDRG4 in a high-temperature environment?
  While the TL082IDRG4 is rated for operation up to 125°C, it's essential to consider the derating of the maximum power dissipation with temperature. Above 85°C, the maximum power dissipation decreases, and the device may not operate within specifications.
• How do I ensure the TL082IDRG4 is stable in my circuit?
  To ensure stability, follow the recommended layout and grounding practices, and use a compensation capacitor (e.g., 10nF to 100nF) between the output and the inverting input. Additionally, avoid capacitive loads and use a resistive load impedance of at least 2kΩ.
• What is the input impedance of the TL082IDRG4?
  The input impedance of the TL082IDRG4 is typically around 10^12 Ω (1TΩ) in common-mode and 10^6 Ω (1MΩ) in differential-mode, making it suitable for high-impedance sources.
• Can I use the TL082IDRG4 as a comparator?
  While the TL082IDRG4 can be used as a comparator, it's not recommended due to its relatively slow slew rate (13V/μs) and limited output current (±20mA). A dedicated comparator like the LM339 or LM2901 would be a better choice.
