10.1 Layout Guidelines
To maintain 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.
