Preliminary specication
Low-cost stereo lter DAC
UDA1320ATS
14 DC CHARACTERISTICS
VDDD =VDDA = 3.3 V; Tamb =25 °C; RL =5k. All voltages referenced to ground (pins 5 and 15) unless otherwise
specied.
Notes
1. All supply connections must be made to the same external power supply unit.
2. When the DAC drives a capacitive load above 50 pF, a series resistance of 100
must be used to prevent
oscillations in the output operational amplifier.
