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 50-ohm transmission lines for input and output signals.
The gain resistor values depend on the desired gain and input impedance of the amplifier. Texas Instruments provides a gain calculation formula in the datasheet, and it's recommended to use a gain resistor value that is within the recommended range to ensure stability and optimal performance.
The maximum input voltage of the LMP8481 is limited by the supply voltage and the input common-mode range. The device can handle input voltages up to the supply voltage, but it's recommended to keep the input voltage within the input common-mode range to ensure optimal performance and prevent damage to the device.
The LMP8481 has a high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR), which helps to reject noise and interference. Additionally, it's recommended to use external filters, such as RC filters or ferrite beads, to further reduce noise and interference in the input signal.
The thermal derating of the LMP8481 is specified in the datasheet, and it's recommended to follow the thermal derating guidelines to ensure the device operates within its recommended operating conditions and to prevent overheating.
