ANALOG INPUT CHARACTERISTICS (AUTOMOTIVE - DNZ) Test Conditions (unless
otherwise specified): Input sine wave (relative to full-scale): 1 kHz through passive input filter; All Supplies = VA; TA = -40 to
+85°C; Sample Frequency = 48 kHz; Measurement Bandwidth is 20 Hz to 20 kHz unless otherwise specified; “Required Initial-
ization Settings” on page 37 written on power up.
VA = 2.37 - 2.63 V
VA = 1.65 - 1.89 V
