Preliminary specification
48 kHz IEC 60958 audio DAC
UDA1352HL
Notes
1.
2.
All supply pins V
DD
and V
SS
must be connected to the same external power supply unit.
When the DAC must drive a higher capacitive load (above 50 pF), a series resistor of 100
must be used to prevent
oscillations in the output stage of the operational amplifier.
The output voltage of the DAC is proportional to the DAC power supply voltage.
