The maximum power dissipation of the TL084CPWR is 1.4W, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 67.5°C/W.
While the TL084CPWR can operate 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 it may affect the device's reliability and lifespan.
To ensure stability, make sure to follow proper PCB layout practices, use a stable power supply, and add decoupling capacitors (e.g., 0.1 μF) close to the op-amp's power pins. Additionally, consider adding a compensation capacitor (e.g., 10 pF) between the output and the inverting input for high-frequency stability.
The recommended input impedance for the TL084CPWR is between 1 kΩ and 100 kΩ. Impedances outside this range may affect the op-amp's performance, such as bandwidth and distortion.
While the TL084CPWR can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (0.5 V/μs) and limited bandwidth (3 MHz). Consider using a dedicated comparator IC, such as the LM339, for comparator applications.
