Texas Instruments recommends a star-ground configuration, 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 ground plane to reduce EMI.
To minimize input bias current effects, use a high-impedance source, such as a voltage divider, and ensure that the input impedance is matched for both inputs. You can also use a bias current cancellation technique, such as a current mirror or a super-beta input stage.
The TLE2084CDWR can drive a maximum capacitive load of 100 pF without oscillation or instability. However, this value may vary depending on the specific application and PCB layout. It's recommended to use a series resistor to dampen the capacitive load and prevent oscillation.
Use a voltage clamp or a transient voltage suppressor (TVS) to protect the op-amp from overvoltage and ESD damage. Additionally, ensure that the PCB layout provides a clear path for ESD discharge to ground, and use ESD-sensitive handling procedures during assembly and testing.
Use a 0.1 μF ceramic capacitor in parallel with a 10 μF tantalum capacitor to decouple the power supply. Place the capacitors as close as possible to the op-amp's power pins, and ensure that the PCB layout provides a low-impedance path for the decoupling capacitors.
