10.1 Layout Guidelines

The layout of the AFE3010 and its surrounding circuit is critical to maintaining performance and minimizing unwanted noise coupling. Follow these layout guidelines:

  • Place all capacitors as close as possible to their respective pins or nodes.
  • Route the signal traces from the 1000-turn coil to the amplifier as a differential pair.
  • Provide low-impedance ground connections throughout the board, especially between the ground pin of the rectifier (D1) and the ground pin of the AFE3010.
  • Connect the bottom AFE3010 thermal pad to board ground to help with noise immunity.
