GENERAL LAYOUT GUIDELINES
For best operational performance of the device, good
printed circuit board (PCB) layout practices are
recommended. Low-loss, 0.1F bypass capacitors
should be connected between each supply pin and
ground, placed as close to the device as possible. A
single bypass capacitor from V+ to ground is
applicable to single-supply applications.
