ANALOG CHARACTERISTICS (AUTOMOTIVE)
Test conditions (unless otherwise specified): VA = 5.0 V +/- 5%; VD = VLS = VLC = 3.3 V +/- 5%;
AGND = DGND = 0 V; TA = -40° to +85° 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 20.
