A good PCB layout for the LMP8358MA/NOPB involves separating the analog and digital grounds, using a solid ground plane, and placing the device close to the analog signal sources. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The choice of gain resistors depends on the desired gain and bandwidth of the amplifier. A higher gain resistor value will result in a higher gain, but may also reduce the bandwidth. TI provides a gain resistor calculator tool to help with the selection.
The maximum power dissipation of the LMP8358MA/NOPB is 1.4W. To ensure you don't exceed it, calculate the power dissipation using the formula Pd = (Vcc x Icc) + (Vout x Iout), and make sure it's within the specified limit. You can also use thermal design and heat sinking to reduce the junction temperature.
To filter out noise and interference, use a combination of passive and active filtering techniques. Use capacitors and resistors to filter out high-frequency noise, and consider adding a low-pass filter or a notch filter to remove specific frequency components. Additionally, use shielding and grounding techniques to minimize electromagnetic interference.
The recommended input impedance for the LMP8358MA/NOPB is 1kΩ to 10kΩ, and the recommended output impedance is 100Ω to 1kΩ. To match the impedance, use a resistive divider or a transformer to match the source impedance to the input impedance, and use a buffer amplifier or a voltage follower to match the output impedance to the load impedance.
