ANALOG OUTPUT CHARACTERISTICS (COMMERCIAL - CNZ)
Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; All Supplies = VA; TA = +25°C;
Sample Frequency = 48 kHz; Measurement bandwidth is 20 Hz to 20 kHz; Test load RL = 10 k, CL = 10 pF for the line output
(see Figure 2); Test load RL = 16 , CL = 10 pF (see Figure 2) for the headphone output; HP_GAIN[2:0] = 011; “Required Initial-
6.
One-half LSB of triangular PDF dither is added to data.
7.
Full-scale output voltage and power is determined by the gain setting, G, in register “Headphone Analog
Gain” on page 51. High gain settings at certain VA and VHP supply levels may cause clipping when the
audio signal approaches full-scale, maximum power output, as shown in Figures 22 - 25 on page 75.
VA = 2.5 V
VA = 1.8 V
