Note 1:

Test condition: BK_O = 1.8V with temperature +25 ºC.

These parameters are characterized but not tested in manufacturing.

Note 1:

fin=1 kHz, B/W=20~20 kHz, A-weighted, THD+N < 0.01%, 0dBFS signal, Load = 100 kOhm.

fin = 1 kHz, B/W = 20~20 kHz, A-weighted, -1dBFS signal, Load=16 Ohm.

fin = 1 kHz, B/W = 20~20 kHz, A-weighted, THD+N < 0.05%, 0dBFS signal, Load = 16 Ohm.

These parameters are characterized but not tested in manufacturing.
