PDN Pulse Width (Note 12)
Note 11. BICK rising edge must not occur at the same time as LRCK edge.
Note 12. The AK4345 can be reset by bringing PDN pin = “L”.
The PDN pulse width is proportional to the value of the capacitor (C) connected to VCOM pin. tPD = 4000
×
C.
When C = 4.7
μ
F, tPD is 19ms(min).
The value of the capacitor (C) connected with VCOM pin should be 1
