The maximum power dissipation of the LM358ADRE4 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 70°C.
While the LM358ADRE4 is an op-amp, it can be used as a comparator in a pinch. However, it's not the best choice for high-speed or high-precision comparator applications due to its limited bandwidth and slew rate. If you need a dedicated comparator, consider using a device like the LM339 or LM2901.
To ensure stability, make sure to follow proper PCB layout practices, such as keeping the input and output traces short and separate, and using a solid ground plane. Additionally, consider adding a capacitor (e.g., 10nF to 100nF) in parallel with the feedback resistor to reduce oscillations. Finally, ensure that the gain and phase margins are sufficient by analyzing the loop gain and phase response.
The input impedance of the LM358ADRE4 is typically around 2MΩ to 5MΩ, depending on the specific application and operating conditions. This is relatively high, making it suitable for use with high-impedance sources or in applications where input impedance is critical.
Yes, the LM358ADRE4 can be used in a single-supply configuration, but you'll need to ensure that the input common-mode voltage range is within the specified limits (typically 0V to VCC-1.5V). You may also need to add a voltage divider or level-shifter to bias the input signals appropriately.
