The maximum power dissipation of TLC2274ID is 670mW at 25°C free-air temperature, but it can be derated to 560mW at 50°C and 450mW at 75°C.
To ensure stability, use a minimum gain of 5, keep the capacitive load below 100pF, and use a 1-10nF capacitor in parallel with a 1-10kΩ resistor in the feedback loop.
Use a star-grounding technique, keep the analog and digital grounds separate, and place the op-amp close to the analog ground. Use a solid ground plane and avoid routing digital signals near the op-amp.
Yes, TLC2274ID can operate up to 125°C, but the maximum junction temperature is 150°C. Ensure proper heat sinking and derate the power dissipation accordingly.
Use a low-pass filter, add a 10-100nF capacitor between the power supply pins, and keep the op-amp away from noise sources. Use a shielded enclosure and ensure good grounding practices.
