Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors to reduce noise and EMI.
Proper power supply decoupling is crucial for the LM98722. Use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) as close as possible to the device's power pins, and consider adding additional decoupling capacitors on the input and output lines.
The LM98722 is rated for operation from -40°C to 125°C, but it's essential to consider the device's thermal characteristics, such as thermal resistance and power dissipation, to ensure reliable operation within the specified temperature range.
To troubleshoot issues with the LM98722, start by verifying the PCB layout, power supply, and decoupling. Use oscilloscopes and spectrum analyzers to measure the device's output and input signals, and consult the datasheet and application notes for guidance on troubleshooting common issues.
The LM98722 is a commercial-grade device, but it can be used in high-reliability or automotive applications with proper design, testing, and validation. Consult with Texas Instruments' application engineers and follow relevant industry standards and guidelines to ensure the device meets the required specifications and standards.
