ANALOG OUTPUT CHARACTERISTICS (AUTOMOTIVE)
(Test Conditions (unless otherwise specified): VA = 5 V±5%, VD = VLS = VLC = 3.3 V±5% and TA = -40 to +85×C.
Full-scale 997 Hz output sine wave (see Note 11) in Figure 25 on page 52 and Figure 25 on page 52; Measure-
ment Bandwidth is 10 Hz to 20 kHz.)
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.
11. One-half LSB of triangular PDF dither is added to data.
12. Guaranteed by design. See Figure 3. RL and CL reflect the recommended minimum resistance and
maximum capacitance required for the internal op-amp's stability and signal integrity. In this circuit to-
pology, CL 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
“External Filters” on page 49 for a recommended output filter.
