ANALOG OUTPUT CHARACTERISTICS (AUTOMOTIVE - DNZ)
Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; All Supplies = VA; TA = -40 to
+85
°C; Sample Frequency = 48 kHz and 96 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 =10pF (see Figure 2) for the headphone output;
HPGAIN[2:0] = 011. “Required Initialization Settings” on page 37 written on power up.
8.
See Figure 2. RL and CL reflect the recommended minimum resistance and maximum capacitance re-
quired for the internal op-amp's stability and signal integrity. In this circuit topology, CL will effectively
move the band-limiting pole of the amp in the output stage. Increasing this value beyond the recom-
mended 150 pF can cause the internal op-amp to become unstable.
VA = 2.37 - 2.63 V
VA = 1.65 - 1.89 V
