Output Gain Setting
Outputs level of AOUTL/AOUTR pin can be selected by GAIN pin.
GAIN pin

L
0dB
H
+6.0dB
open
+12dB
Note 15. Output level of AOUTL/AOUTR pin clips if it exceeds 2Vrms.
The input data should be 2Vrms or less as the output level.

Soft Mute Operation
Soft mute operation is performed at digital domain. When the SMUTE pin goes to “H”, the output signal is attenuated by
-
∞
during 1024 LRCK cycles. When the SMUTE pin is returned to “L”, the mute is cancelled and the output attenuation
gradually changes to 0dB during 1024 LRCK cycles. If the soft mute is cancelled within the 1024 LRCK cycles after
starting the operation, the attenuation is discontinued and returned to 0dB by the same cycle. The soft mute is effective for
changing the signal source without stopping the signal transmission.

Notes:
(1) 1020LRCK cycles (1020/fs) at input data is attenuated to -

.
(2) The analog output corresponding to the digital input has a group delay, GD.
(3) If the soft mute is cancelled before attenuating to -
∞
after starting the operation, the attenuation is discontinued and
returned to ATT level by the same cycle.

System Reset
The AK4341 must be reset once by bringing PDN pin = “L” upon power-up. The AK4341 is powered up and the internal
timing starts clocking by LRCK “
↑
” after exiting reset and power down state by MCLK. The AK4341 is in the
power-down mode until LRCK are input.
