Power-down
The AK4341 is placed in the power-down mode by bringing PDN pin “L” and the analog outputs are VCOM voltage
(VDD). Figure 4 shows an example of the system timing at the power-down and power-up.

Notes:
(1) The analog output corresponding to digital input has the group delay (GD).
(2) Analog outputs are VCOM level (VDD) at the power-down mode.
(3) Click noise occurs at the edge of PDN signal. This noise is output even if “0” data is input.
(4) The external clocks (MCLK, BICK and LRCK) can be stopped in the power-down mode (PDN = “L”).
(5) Please mute the analog output externally if the click noise (3) influences system application.
The timing example is shown in this figure.
