The maximum power dissipation of the LM318MX/NOPB is 670mW, which is calculated based on the maximum junction temperature (Tj) of 150°C and the thermal resistance (RθJA) of 125°C/W.
While the LM318MX/NOPB 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 (1MHz). A dedicated comparator like the LM339 or LM2901 would be a better option.
To ensure stability, make sure to follow proper PCB layout practices, use a low-ESR capacitor for decoupling, and consider adding a compensation capacitor (e.g., 10nF to 100nF) in parallel with the feedback resistor to reduce oscillations.
The input impedance of the LM318MX/NOPB is typically around 2MΩ, which is relatively high. This makes it suitable for use with high-impedance sources or in applications where a high input impedance is required.
Yes, the LM318MX/NOPB can be used in a single-supply configuration, but you'll need to ensure that the input signals are referenced to the midpoint of the supply voltage (Vcc/2) to maintain a stable output.
