Notes: 10.
Guaranteed by design. The DC current draw represents the allowed current draw from the AOUT pin
due to typical leakage through the electrolytic DC blocking capacitors.
One-half LSB of triangular PDF dither is added to data.
Guaranteed by design. See Figure 2. R
L
and C
L
reflect the recommended minimum resistance and
maximum capacitance required for the internal op-amp's stability and signal integrity. In this circuit
topology, C
L
will effectively move the dominant pole of the two-pole amp in the output stage. Increasing
this value beyond the recommended 100 pF can cause the internal op-amp to become unstable. See
Appendix A for a recommended output filter.
