ANALOG OUTPUT CHARACTERISTICS (AUTOMOTIVE - DNZ)
(Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; measurement
bandwidth is 10 Hz to 20 kHz; Sample Frequency = 48 kHz and 96 kHz; test load RL = 10 kΩ, CL = 10 pF for the
line output (see Figure 3), and test load RL = 16 Ω, CL = 10 pF (see Figure 3) for the headphone output.
HP_GAIN[2:0] = 011.)
