• Manufacturer Part Number: AK4396VF
• Description: Advanced Multi-Bit 192kHz 24-Bit ?? DAC
• Manufacturer: AKM [Asahi Kasei Microsystems]

ASAHI KASEI
2. Auto Setting Mode (ACKS pin = “H”)
MCLK frequency and the sampling speed are detected automatically (Table 4) and DFS0 pin is ignored. DFS0 pin should
be fixed to DVSS or DVDD.
(2) Serial Mode (P/S pin = “L”)
1. Manual Setting Mode (ACKS bit = “0”)
MCLK frequency is detected automatically and the sampling speed is set by DFS1-0 bits (Table 6). The MCLK frequency
corresponding to each sampling speed should be provided (Table 7). The AK4396 is set to Manual Setting Mode at
power-up (PDN pin = “L” → “H”). When DFS1-0 bits are changed, the AK4396 should be reset by RSTN bit.
