The datasheet provides general guidelines, but a good rule of thumb is to keep the analog and digital grounds separate, and to place the device close to the analog signal sources to minimize noise. A 4-layer PCB with a solid ground plane is recommended.
Consult the application notes and design notes provided by Linear Technology, and consider factors such as input signal amplitude, frequency, and impedance, as well as the desired output data rate and resolution. Simulation tools like LTspice can also be helpful.
The device has a maximum junction temperature of 150°C. Ensure good thermal conduction by using a heat sink or thermal pad, and avoid overheating by keeping the device within the recommended operating temperature range.
Yes, the device can operate with multiple voltage rails, but ensure that the analog and digital supplies are properly decoupled and that the device is operated within the recommended voltage ranges.
Consult the troubleshooting guide in the datasheet, and consider factors such as input signal quality, PCB layout, and power supply noise. Use tools like oscilloscopes and logic analyzers to debug the issue.
