Texas Instruments recommends a star-ground 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 each other, and use a ground plane to reduce noise and EMI.
To minimize the effects of high input bias current, use a low-impedance source, such as a voltage divider or a buffer amplifier, and consider using a bias current cancellation technique. Additionally, ensure that the input signal is within the op-amp's common-mode range.
The TLE2144MDWG4 can drive a maximum capacitive load of around 100 pF to 200 pF, depending on the application and the desired stability. Exceeding this limit may cause oscillations or instability.
To ensure stability in high-gain configurations, use a compensation capacitor between the output and the inverting input, and consider adding a series resistor to the feedback path. Additionally, ensure that the op-amp's bandwidth is sufficient for the desired gain and frequency response.
Texas Instruments recommends using a 0.1 μF to 1 μF ceramic capacitor in parallel with a 10 μF to 22 μF tantalum or electrolytic capacitor for power supply decoupling. This helps to reduce noise and ensure stable operation.
