A good PCB layout for the AD8418 involves keeping the input traces as short as possible, using a solid ground plane, and placing the input capacitors close to the device. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog ground plane to minimize noise and interference.
The AD8418 has an internal calibration circuit that sets the gain and offset of the device. However, for optimal performance, it's recommended to perform an external calibration using an external voltage reference and a precision resistor network to set the gain and offset to the desired values.
The maximum allowed input voltage for the AD8418 is ±25V, but it's recommended to keep the input voltage within ±20V to ensure optimal performance and to prevent damage to the device.
To minimize EMI and RFI interference, it's recommended to use a shielded enclosure, keep the input cables as short as possible, and use twisted pair cables with a shielded drain wire. Additionally, using a common-mode filter or a ferrite bead on the input lines can help to reduce interference.
It's recommended to use a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor to decouple the power supply. This helps to reduce noise and ripple on the power supply lines and ensures optimal performance of the AD8418.
