9. Analog Performance Characteristics
The measurements are performed under the circumstance as:
T_ambient = 25℃, AVdd = 5.0V ± 5%, DVdd = 3.3V ± 5%, 10kΩ/50pF
external load. Input is 1 kHz sine wave; Sampling frequency = 48 kHz;
Bandwidth = 20 to 20 kHz; 0dB attenuation; All sound effects such as
3D effects are disabled.
