ANALOG CHARACTERISTICS
Test conditions (unless otherwise specified): VA = 5 V; VD = VLS = VLC = 3.3 V; AGND = DGND = 0 V;
T
A
= +25° C; Input test signal: 1 kHz sine wave; measurement bandwidth is 10 Hz to 20 kHz; Fs = 48/96/192 kHz;
PGA gain = 0 dB; All connections as shown in Figure 7 on page 18 .
3. Valid for Double- and Quad-Speed Modes only.
4. Referred to the typical A/D full-scale input voltage
5. Valid when the microphone-level inputs are selected.
