ADC 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; TA = -10° to +70° C for Commercial or -40° to
+85° C for Automotive; Input test signal: 1 kHz sine wave; measurement bandwidth is 10 Hz to 20 kHz;
Fs = 48/96/192 kHz. Synchronous mode; All connections as shown in Figure 12 on page 29.
