The maximum power dissipation of the LMC6484AIMX is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
To ensure stability, add a 10nF to 22nF capacitor in parallel with a 1kΩ to 2kΩ resistor between the output and the inverting input. This helps to reduce the phase margin and prevent oscillations.
Use a star-ground configuration, keep the input and output traces short and away from each other, and avoid running digital signals near the op-amp. Also, use a ground plane and decouple the power supply with a 10uF capacitor.
While the LMC6484AIMX can be used as a comparator, it's not the best choice due to its relatively slow slew rate (0.5V/us) and limited bandwidth (1.5MHz). A dedicated comparator like the LM339 or LM2901 would be a better option.
Use an anti-static wrist strap or mat, and handle the device by the body or pins, not the leads. Store the device in an anti-static bag or tube, and avoid touching the pins or leads during handling.
