• Manufacturer Part Number: ak5365
• Description: 24-bit 96khz ?? Adc With Selector/pga/alc
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
The M/S pin selects either master or slave mode. M/S pin = “H” selects master mode and “L” selects slave mode. The
AK5365 outputs BICK and LRCK in master mode. In slave mode, MCLK, BICK and LRCK are input externally.
The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 1.0Hz
(@fs=48kHz) and scales with sampling rate (fs).
