... In parallel mode (P/S pin = “H”), all external clocks (MCLK, BICK and LRCK) should always be present whenever the DAC is in normal operation mode (PDN pin = “H”). If these clocks are not provided, the AK4366 may draw excess current and will not operate properly because it utilizes these clocks for internal dynamic refresh of registers. If the external clocks are not present, the DAC should be placed in power-down mode (PDN pin = “ ...

... ASAHI KASEI Digital Attenuator The AK4366 has a channel-independent digital attenuator (256 levels, 0.5dB step). This digital attenuator is placed before the D/A converter. ATTL/R7-0 bits set the attenuation level (0dB to −127dB or MUTE) for each channel (Table 5). At DATTC bit = “1”, ATTL7-0 bits control both Lch and Rch attenuation levels. At DATTC bit = “0”, ATTL7-0 bits control the Lch level and ATTR7-0 bits control the Rch level. In parallel mode (P/S pin = “ ...
