Note 3. DACL=DACR bits = “1”, MINL=MINR=LINL=RINR bits = “0”, ATTL=ATTR=0dB.
Note 4. AC Load
Note 5. Output voltage is proportional to VDD voltage. Vout = 0.47 x VDD(typ)@
4.8dBFS.
Note 6. DACM bit = “1”, DACL=DACR bits = “0”, LINM=RINM=MINM bits = “0”, ATTL=ATTR=ATTM=0dB, and
common mode signal is input to L/Rch of DAC.
Note 7. Output voltage is proportional to VDD voltage. Vout = 0.66 x VDD(typ).
