A bypass capacitor should always be used with this device, placed as close as possible to the device pin. A bypass capacitor value of 1 µF is recommended. Digital and analog traces should be separated as much as possible on the board, with no traces running underneath the device or the bypass capacitor. Extra precautions should be taken to keep traces with high frequency signals (such as clock lines) as far as possible from analog traces. Use of an analog ground plane is recommended in order to keep the ground potential the same for all devices on the board. Providing VDD connections to devices in a “star” configuration can also reduce noise by eliminating return current paths and associated errors (see Figure 6-4). For more information on layout tips when using A/D converters, refer to AN688, “Layout Tips for 12-Bit A/D converter Applications” .
