Notes:
(1) Mute the analog outputs externally if click noise (1) adversely affects the system.
(2) In case of the CAL bit = “1”, the offset calibration is always executed when the source of TVOUTL/R pins are
switched to AMP after the STBY bit is changed to “0”. To disable this function, set the CAL bit = “0”.
