8.6 Analog Performance
The measurements are performed under the circumstance as:
Tambient = 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.
