ANALOG OUTPUT CHARACTERISTICS (COMMERCIAL - CNZ)
(Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; VD = 1.8 V;
VL_HD = VL_IF = 3.3V; TA = +25C; Measurement bandwidth is 10 Hz to 20 kHz; test load RL = 10 k CL = 10 pF
for the line output and test load RL = 16  CL = 10 pF for the headphone output (see Figure 3); DAC Gain = 0 dB).
