The maximum power dissipation of the TL084QDG4 is dependent on the package and ambient temperature. For the QDG4 package, the maximum power dissipation is 1.4W at 25°C free-air temperature. However, this value can be derated based on the ambient temperature and package thermal resistance.
While the TL084QDG4 is an op-amp, it can be used as a comparator in certain applications. However, it's not recommended as a dedicated comparator due to its limited slew rate and bandwidth. Additionally, the output stage is not designed to drive low-impedance loads, which may lead to oscillations or instability.
The input impedance of the TL084QDG4 is typically around 2MΩ, but it can vary depending on the specific application and operating conditions. This is relatively high compared to other op-amps, making it suitable for high-impedance sources.
Yes, the TL084QDG4 can be used in a single-supply configuration, but it requires careful consideration of the input common-mode range and output voltage swing. The device can operate from a single supply voltage as low as 4V, but the input common-mode range is limited to within 2V of the supply rails.
The TL084QDG4 has a relatively low noise floor, with a typical input voltage noise density of 18nV/√Hz and a typical input current noise density of 0.01pA/√Hz. However, the noise performance can be affected by the operating conditions, such as supply voltage and temperature.
