DAC ANALOG CHARACTERISTICS

Test Conditions (unless otherwise specified): AGND = DGND = 0 V; VA = 3.13 V to 5.25 V; VD = 3.13 V to 5.25 V
or VA + 0.25 V, whichever is less; VLS = VLC = 1.71 V to 5.25 V; T
+85° C for Automotive; Output test signal: 997 Hz full-scale sine wave; Test load R
Figure 1), Fs = 48/96/192 kHz. Measurement Bandwidth 10 Hz to 20 kHz; All Connections as shown in
page 23.

4. One-half LSB of triangular PDF dither added to data.
5. 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.
