Layout Guidelines (continued)

4. Avoid placing vias between the VDD and bypass capacitors.

5. Connect ground pin to the ground plane using short, low-impedance path.

6. The fly-wheel RC filters are placed close to the device.

Among ceramic surface-mount capacitors, COG (NPO) ceramic capacitors provide the best capacitance

precision. The type of dielectric used in COG (NPO) ceramic capacitors provides the most stable electrical

properties over voltage, frequency, and temperature changes.
