5. 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.
ANALOG PASSTHROUGH CHARACTERISTICS
Test Conditions (unless otherwise specified): Input sine wave (relative to full-scale): 1 kHz through passive input filter;
