The maximum power dissipation of LP324MT/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.
Yes, LP324MT/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 layout and compensation techniques, such as using a compensation capacitor (Cc) and a bypass capacitor (Cb) as recommended in the datasheet. Additionally, the gain and phase margin should be checked to ensure stability.
The input impedance of LP324MT/NOPB is typically around 1MΩ, but it can vary depending on the specific application and operating conditions. It's essential to consider the input impedance when designing the circuit to ensure proper operation.
While LP324MT/NOPB can be used as a comparator, it's not the most suitable device for this application. The LP324MT/NOPB is an op-amp designed for linear applications, and its performance as a comparator may not be optimal. Texas Instruments recommends using a dedicated comparator device, such as the LM339, for comparator applications.
