ANALOG OUTPUT CHARACTERISTICS (AUTOMOTIVE - DNZ)
Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; All Supplies = VA; T
+85°C; Sample Frequency = 48 kHz and 96 kHz; Measurement bandwidth is 20 Hz to 20 kHz; Test load R
for the line output (see
HPGAIN[2:0] = 011.

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.
