A good PCB layout for OPA387DBVR involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated analog ground plane is recommended.
The choice of gain resistors depends on the desired gain, bandwidth, and noise requirements. A good starting point is to use the gain resistor values recommended in the datasheet, and then adjust them based on the specific application requirements. It's also important to consider the resistor's tolerance, temperature coefficient, and parasitic capacitance.
The maximum power dissipation of OPA387DBVR is 750mW. To ensure you don't exceed it, calculate the power dissipation based on the output current, voltage, and package thermal resistance. Use thermal design and layout techniques such as heat sinks, thermal vias, and thermal pads to reduce the junction temperature.
Use a combination of passive and active filtering techniques, such as RC filters, ferrite beads, and shielding, to reduce noise and interference. Also, consider using a low-pass filter or a notch filter to remove specific frequency components. Additionally, ensure good PCB layout practices, such as separating analog and digital grounds, and using decoupling capacitors.
The recommended operating voltage range for OPA387DBVR is 2.7V to 5.5V. Operating the device outside this range may affect its performance, reliability, and lifespan.
