The maximum power dissipation of the TL082IDRE4 is dependent on the ambient temperature and the package thermal resistance. According to the datasheet, the maximum power dissipation is 670mW at 25°C ambient temperature, but this can be derated to 500mW at 50°C and 330mW at 85°C.
While the TL082IDRE4 is an op-amp, it can be used as a comparator in a pinch. However, it's not the best choice for this application due to its limited slew rate and bandwidth. Texas Instruments recommends using a dedicated comparator like the LM339 or LM2901 for comparator applications.
The input impedance of the TL082IDRE4 is typically around 10^12 ohms in parallel with 10-20pF of input capacitance. This is relatively high, making the TL082IDRE4 suitable for high-impedance signal sources.
Yes, the TL082IDRE4 can be used in a single-supply configuration, but the input common-mode voltage range is limited to within 2V of the positive supply rail. This means that the input signal should be biased to be within this range to ensure proper operation.
The TL082IDRE4 can source or sink up to 10mA of output current, making it suitable for driving small loads like resistors, capacitors, or small transistors. However, it's not suitable for driving heavy loads or inductive loads.
