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.
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.
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.
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.
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.
