• Manufacturer Part Number: AK5373
• Description: 24-bit Stereo ADC with USB Interface
• Manufacturer: AKM [Asahi Kasei Microsystems]

In normal mute operation (OSME bit = “0”), mute is executed on zero cross or zero cross timeout when the LMUTEN and
RMUTEN pins = “L” if zero cross detection is enabled. When zero cross detection is disabled, it is executed immediately.
In case that the LMUTEN and RMUTEN pins = “H”, mute is released on zero cross or zero cross timeout if the zero cross
detection is enabled. When zero cross detection is disabled, it is released immediately.
In one-shot mute operation (OSME bit = “1”), mute is executed on zero cross or zero cross timeout after detecting a falling
edge of the LMUTEN and RMUTEN pins. The AK5373 releases the mute on zero cross or zero cross timeout after mute
hold period which is set by MHLD7-0 bits.
