■DAC OUTPUT VOLTAGE CHARACTERISTICS
■DAC OUTPUT VOLTAGE FORMULA IN IDEAL CONDITIONS
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.
