The maximum power dissipation of the LM358PWG4 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, and it decreases as the temperature increases.
While the LM358PWG4 is an op-amp, it can be used as a comparator in certain applications. However, it's not recommended for high-speed or high-frequency comparator applications due to its limited slew rate and bandwidth. Additionally, the output stage is not designed to drive low-impedance loads, which may be required in some comparator applications.
The input impedance of the LM358PWG4 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 sensor applications.
Yes, the LM358PWG4 can be used in a single-supply configuration, but it requires careful consideration of the input common-mode voltage range and the output voltage swing. The device can operate from a single supply voltage as low as 3V, but the input common-mode voltage range is limited to within 1.5V of the supply rails.
The LM358PWG4 is not the best choice for audio applications due to its limited bandwidth (1MHz) and high noise floor. It's better suited for low-frequency, low-gain applications such as sensor conditioning, instrumentation, and industrial control systems.
