Notes:
(1) The analog output corresponding to the digital input has a group delay, GD.
(2) The external clocks (MCLK, BICK and LRCK) can be stopped in standby mode.
(3) Please mute the analog outputs externally if click noise(3) adversely affects the system.
(4) In case of the CAL bit = “1”, the offset calibration is always executed when the source of TVOUT is switched to
DAC after the STBY bit is changed to “0”. To disable this function, set the CAL bit = “0”.
