DAC ANALOG CHARACTERISTICS
(Full-Scale Output Sine Wave, 997 Hz; Test load R
L
= 3 k
,
C
L
= 10 pF (see Figure 1), Fs = 48/96/192 kHz. Measurement Bandwidth 10 Hz to 20 kHz, unless otherwise speci-
fied.) Synchronous mode.
Note:
3. One-half LSB of triangular PDF dither added to data.
4.
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.
5.
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. C
L
affects the dominant pole of the
internal output amp; increasing C
L
beyond 100 pF can cause the internal op-amp to become unstable.
