LF347DR Frequently Asked Questions (FAQ)

  • The maximum power dissipation of the LF347DR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.

  • While the LF347DR is an op-amp, it can be used as a comparator in certain applications. However, it's not recommended as it's not optimized for comparator applications and may not provide the best performance. TI recommends using a dedicated comparator like the LM339 or LM2901 for comparator applications.

  • To minimize noise and oscillations, keep the input and output traces short and away from each other, use a solid ground plane, and decouple the power supply with capacitors. Also, consider using a ferrite bead or a resistor in series with the output to reduce oscillations.

  • A 0.1uF ceramic capacitor is a good starting point for decoupling the power supply of the LF347DR. However, the optimal value may vary depending on the specific application and PCB layout.

  • The LF347DR is rated for operation up to 125°C, but its performance may degrade at high temperatures. If you need to operate the device in a high-temperature environment, consider using a more temperature-stable op-amp like the OPA277 or OPA827.
