Recommendations that optimize performance include: 1. Minimize parasitic capacitance from the signal I/O pins to AC ground. Parasitic capacitance on the output and inverting input pins can cause instability. To reduce unwanted capacitance, TI recommends cutting out the power and ground traces underneath the signal input and output pins. Otherwise, ground and power planes must be unbroken elsewhere on the board. When configuring the amplifier as a TIA, if the required feedback capacitor is under 0.15 pF, consider using two series resistors, each of half the value of a single resistor in the feedback loop to minimize the parasitic capacitance from the resistor. 2. Minimize the distance (less than 0.25") from the power-supply pins to high-frequency bypass capacitors. Use high quality, 100-pF to 0.1-µF, C0G and NPO-type decoupling capacitors with voltage ratings at least three times greater than the amplifiers maximum power supplies to ensure that there is a low-impedance path to the amplifiers power-supply pins across the amplifiers gain bandwidth specification
