ANALOG INPUT CHARACTERISTICS (COMMERCIAL - CNZ)
(Test Conditions (unless otherwise specified): Input sine wave (relative to digital full-scale): 1 kHz through passive
input filter; VA_HP = VA; VL_HD = VL_IF = 3.3; VD = 1.8 V; T_A = +25°C; Measurement Bandwidth is 10 Hz to
20 kHz unless otherwise specified. Sample Frequency = 48 kHz)
VA, VA_REF = 5.0 V
