ANALOG CHARACTERISTICS (AUTOMOTIVE - DNZ)
(Test Conditions (unless otherwise specified): Input sine wave (relative to full scale): 1 kHz through passive input
filter; Measurement Bandwidth is 10 Hz to 20 kHz unless otherwise specified. Sample Frequency = 48 kHz)
4. Referred to the typical full-scale voltage. Applies to all THD+N and Dynamic Range values in the table.
5. Measured between AINxx and AGND.
VA = 2.5 V (nominal)
VA = 1.8 V (nominal)
