Notes to the operation
1. Both a ground and a supply planes in a PCB should be as wide as possible for reducing a parasitic
inductance and resistance. Especially, for the better performance, the analog plane needs to be much wider.
2. A tantalum or electrolytic capacitor of 10µF or more and a ceramic capacitor of 0.01µF are tied together,
which are connected between a digital supply and ground, also between a analog supply and ground. These
capacitors should be placed as close as possible to the IC. They work as bypass capacitors for preventing a
degradation in the performance by a supply voltage fluctuation caused by digital signals including a clock
and digital inputs and so on.
3. The analog output should be isolated as much as possible from a clock and digital inputs, thus minimizing
decoupling and interactive noise.
