The maximum power dissipation of the TLE2021CD 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 in a unity-gain configuration, it's recommended to add a capacitor (typically 10-22pF) between the output and the inverting input to compensate for the internal pole.
To minimize noise and oscillations, it's recommended to keep the input and output traces short and away from each other, use a solid ground plane, and decouple the power supply with a 0.1uF capacitor.
While the TLE2021CD can be used as a comparator, it's not recommended due to its relatively slow slew rate (0.5V/us) and limited output current (±20mA). A dedicated comparator like the LM339 or LM2901 is a better choice for comparator applications.
To protect the TLE2021CD from input overvoltage, it's recommended to add input clamping diodes (e.g., 1N4148) and a series resistor to limit the input voltage to the maximum rating of 16V.
