Notes:

1. Preventing Switching Noise

To prevent switching noise in the analog output signal, connect noise limiting capacitors to the VCCA and

VCCD pins as close to the A.GND and D.GND pins as possible.

2. Power Pattern

To reduce parasitic impedance, the PC board pattem to the VCCA, VCCD, A.GND and D.GND pins should

be as wide as possible.
