LMV358IDDUR datasheet by Texas Instruments

LMV358IDDUR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LMV358IDDUR?
  The maximum power dissipation of the LMV358IDDUR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
• Can I use the LMV358IDDUR in a high-temperature environment?
  Yes, the LMV358IDDUR is rated for operation from -40°C to 125°C, making it suitable for high-temperature applications. However, the device's performance may degrade at higher temperatures, and the maximum junction temperature should not be exceeded.
• How do I ensure stability when using the LMV358IDDUR in a feedback loop?
  To ensure stability, it's essential to follow proper compensation techniques, such as adding a capacitor in parallel with the feedback resistor to reduce the gain-bandwidth product. Additionally, the datasheet provides guidance on stability analysis and compensation methods.
• What is the input impedance of the LMV358IDDUR?
  The input impedance of the LMV358IDDUR is typically around 10^12 ohms in parallel with 2pF, making it suitable for high-impedance sources and minimizing the loading effect on the input signal.
• Can I use the LMV358IDDUR as a comparator?
  While the LMV358IDDUR can be used as a comparator, it's not the most suitable device for this application. The device's output stage is optimized for linear operation, and its response time may be slower than a dedicated comparator. For comparator applications, a dedicated comparator IC like the LMV761 is recommended.
