LM358ADE4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of LM358ADE4?
  The maximum power dissipation of LM358ADE4 is 670mW when operating at 25°C with a 5V supply voltage. However, this value can vary depending on the ambient temperature and supply voltage.
• Can I use LM358ADE4 as a comparator?
  Yes, LM358ADE4 can be used as a comparator, but it's not recommended due to its limited bandwidth and slew rate. The LM358 is primarily designed as an op-amp, and its performance as a comparator may not be optimal. If you need a dedicated comparator, consider using a device like the LM339 or LM2901.
• How do I calculate the input impedance of LM358ADE4?
  The input impedance of LM358ADE4 is typically around 2MΩ to 5MΩ, depending on the frequency and operating conditions. You can calculate the input impedance using the formula: Zin = (Vin / Iin), where Vin is the input voltage and Iin is the input current.
• Is LM358ADE4 suitable for audio applications?
  LM358ADE4 can be used for audio applications, but it's not the best choice due to its limited bandwidth (1.2MHz) and high noise floor. For audio applications, consider using a dedicated audio op-amp like the OPA2134 or OPA2140, which offer better noise performance and higher bandwidth.
• Can I use LM358ADE4 in a single-supply configuration?
  Yes, LM358ADE4 can be used in a single-supply configuration, but you'll need to ensure that the input voltage is within the common-mode input voltage range (VCC-1.5V to VCC+0.5V). Additionally, you may need to add external components to bias the input signals to the correct voltage level.
