12 Layout

12.1 Layout Guidelines

To ensure reliability of the device, follow common printed-circuit board (PCB) layout guidelines:

  • Leads to the input must be as direct as possible with a minimum conductor length.
  • The ground path must have low resistance and low inductance.
  • Use short trace-lengths to avoid excessive loading.
  • It is common to have a dedicated ground plane on an inner layer of the board.
  • Terminals that are connected to ground must have a low-impedance path to the ground plane in the form of wide polygon pours and multiple vias.
  • Use bypass capacitors on power supplies and placed them as close as possible to the VDD pin.
  • Apply low equivalent series resistance (0.1-μF to 10-μF tantalum or electrolytic capacitors) at the supplies to minimize transient disturbances and to filter low-frequency ripple.
  • To reduce the total I2C bus capacitance added by PCB parasitics, data lines (SCL and SDA) must be as short as possible and the widths of the traces must also be minimized (for example, 5 to 10 mils depending on copper weight).
