LM358AMX datasheet by Texas Instruments

LM358AMX Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM358AMX?
  The maximum power dissipation of the LM358AMX is 670mW, which is calculated based on the maximum junction temperature (Tj) of 150°C and the thermal resistance (RθJA) of 125°C/W.
• Can I use the LM358AMX as a comparator?
  While the LM358AMX can be used as a comparator, it's not the best choice due to its relatively slow slew rate (0.5V/μs) and limited bandwidth (1.2MHz). A dedicated comparator like the LM339 or LM2901 would be a better option.
• How do I ensure stability when using the LM358AMX in a feedback loop?
  To ensure stability, make sure to add a capacitor (typically 10nF to 100nF) between the output and the inverting input to compensate for the op-amp's internal capacitance and prevent oscillations.
• What is the input impedance of the LM358AMX?
  The input impedance of the LM358AMX is typically around 2MΩ, which is relatively high, making it suitable for high-impedance sources.
• Can I use the LM358AMX in a single-supply configuration?
  Yes, the LM358AMX 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 (VCM) of -0.3V to VCC-1.5V.
