Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-frequency design practices, such as using a solid ground plane, minimizing trace lengths, and avoiding vias under the device. Additionally, ensure that the analog and digital grounds are separated and connected at a single point.
To minimize high-frequency noise and EMI, use a low-pass filter on the input signals, and consider adding a ferrite bead or a common-mode choke to the power supply lines. Also, ensure that the device is properly decoupled, and the PCB layout is optimized for minimal radiation.
While the datasheet specifies a maximum operating frequency of 100 MHz, the actual frequency limit depends on the specific application, signal amplitude, and PCB layout. In general, it's recommended to operate the device at frequencies below 50 MHz to ensure reliable performance.
The choice of resistors depends on the specific application and signal requirements. As a general guideline, use resistors with a tolerance of 1% or better, and consider using resistors with a high-frequency rating (e.g., thin-film or metal-film resistors). The datasheet provides recommended resistor values, but you may need to adjust them based on your specific design requirements.
To ensure proper operation, power up the device in the following sequence: VCC, VEE, and then the input signals. This sequence helps prevent latch-up and ensures that the device is properly biased.
