The maximum power dissipation of the OP07DD 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 buffer configuration, it's recommended to add a capacitor (typically 10-100pF) between the output and the inverting input to prevent oscillations.
To minimize noise and EMI, it's recommended to keep the input and output traces short and away from each other, use a ground plane, and decouple the power supply with a 0.1uF capacitor.
While the OP07DD can be used as a comparator, it's not recommended due to its relatively slow slew rate (0.5V/us) and limited bandwidth (10kHz). A dedicated comparator like the LM339 or LM2901 is a better choice.
The input bias current of the OP07DD is typically 10nA, which can cause voltage offsets. To minimize this effect, use a high-impedance input source, add a bias current compensation resistor, or use a chopper-stabilized op-amp like the OP07CP.
