The maximum power dissipation of the LME49710HA 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 pins to compensate for the op-amp's internal capacitance and ensure stability.
To minimize noise and EMI, it's recommended to follow good PCB layout practices, such as keeping the input and output traces separate, using a solid ground plane, and placing decoupling capacitors close to the op-amp's power pins.
The LME49710HA is rated for operation up to 125°C, but its performance may degrade at higher temperatures. If you need to operate the op-amp in a high-temperature environment, consider using a heat sink or a thermally-enhanced package.
Choose resistors and capacitors that meet the op-amp's bandwidth and noise requirements. For example, use low-noise, high-precision resistors and capacitors with low equivalent series resistance (ESR) to minimize noise and distortion.
