Texas Instruments recommends a star-grounded layout, with the op-amp's ground pin connected to a central ground point. Additionally, keep the input and output traces short and away from noise sources, and use a solid ground plane to reduce electromagnetic interference (EMI).
The TLE2064AMDR has a relatively high input bias current (up to 100 nA). To minimize its effect, use a high-impedance input source, and consider adding a bias current compensation network (e.g., a resistor and capacitor in series) to cancel out the input bias current.
The TLE2064AMDR can drive up to 1 nF of capacitive load without oscillating, but this value may vary depending on the specific application and PCB layout. To ensure stability, it's recommended to add a series resistor (e.g., 22 Ω) to the output stage to dampen the capacitive load.
Use a voltage clamp or a transient voltage suppressor (TVS) diode to protect the op-amp from overvoltage conditions. Additionally, follow proper ESD handling procedures when handling the device, and consider adding ESD protection devices (e.g., diodes or resistors) to the input and output stages.
Use a combination of ceramic and electrolytic capacitors to decouple the power supply. A 0.1 μF ceramic capacitor and a 10 μF electrolytic capacitor in parallel, placed close to the op-amp's power pins, can provide effective decoupling and noise filtering.
