TL082CN datasheet by STMicroelectronics

TL082CN Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL082CN?
  The maximum power dissipation of the TL082CN is 670mW, which is calculated based on the maximum junction temperature (Tj) of 150°C and the thermal resistance (Rthja) of 125°C/W.
• Can I use the TL082CN as a comparator?
  While the TL082CN 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 TL082CN in a feedback loop?
  To ensure stability, make sure to use a compensation capacitor (e.g., 10nF to 100nF) between the output and the inverting input. This helps to reduce oscillations and improve phase margin.
• What is the input impedance of the TL082CN?
  The input impedance of the TL082CN is typically around 2MΩ, which is relatively high. This makes it suitable for use in high-impedance circuits or as a buffer amplifier.
• Can I use the TL082CN in a single-supply configuration?
  Yes, the TL082CN can be used in a single-supply configuration, but you'll need to ensure that the input voltage is within the common-mode input voltage range (VCC- to VCC+). You may also need to add a voltage divider or level shifter to adjust the input voltage.
