LMH6645MFX/NOPB Frequently Asked Questions (FAQ)
-
The maximum power dissipation of the LMH6645MFX/NOPB is 1.4W, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 57.1°C/W.
-
Yes, the LMH6645MFX/NOPB is rated for operation from -40°C to 125°C, making it suitable for high-temperature applications. However, the maximum junction temperature (TJ) should not exceed 150°C.
-
To ensure stability, it's essential to follow proper compensation techniques, such as adding a capacitor in parallel with the feedback resistor or using a series resistor-capacitor (RC) network in the feedback path.
-
To minimize noise and ensure proper operation, it's recommended to use a star-grounding technique, where the grounds of the power supplies, analog circuits, and digital circuits are connected at a single point. Additionally, keep the layout compact, and use short traces to minimize parasitic inductance and capacitance.
-
While the LMH6645MFX/NOPB can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (10V/μs) and limited output current (±20mA). A dedicated comparator IC would be a better choice for most applications.
