A good PCB layout practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the high-frequency signals away from the analog signals. Additionally, use a common-mode choke or a ferrite bead to filter the power supply lines.
Make sure to follow the power-up sequence specified in the datasheet, and ensure that the VCC and VEE pins are properly decoupled. Also, configure the device according to the application note and datasheet recommendations.
The maximum cable length supported by the MAX3491EESD+T depends on the specific application and the type of cable used. As a general guideline, the device can support cable lengths up to 100 meters, but this may vary depending on the specific use case.
To troubleshoot issues with the MAX3491EESD+T, start by checking the power supply and configuration. Use an oscilloscope to verify the signal integrity and check for any signs of signal degradation. Also, consult the application note and datasheet for troubleshooting guidelines.
The MAX3491EESD+T has a maximum junction temperature of 150°C. Ensure good airflow around the device, and consider using a heat sink if the device is expected to operate in high-temperature environments.
