The maximum power dissipation of the TL084IDR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (RθJA) of 125°C/W.
Yes, the TL084IDR is rated for operation from -40°C to 125°C, making it suitable for high-temperature applications. However, the maximum junction temperature (TJ) should not exceed 150°C.
To ensure stability, it's essential to follow proper compensation techniques, such as adding a capacitor in parallel with the feedback resistor to reduce the gain-bandwidth product. Additionally, the datasheet provides guidance on selecting the correct compensation components.
The input impedance of the TL084IDR is typically around 2MΩ, which is relatively high. This makes it suitable for applications where a high input impedance is required, such as in audio circuits.
While the TL084IDR can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (0.5V/μs) and limited bandwidth (3MHz). A dedicated comparator IC would be a better choice for most applications.
