• Manufacturer Part Number: ak4395
• Description: Advanced Multi-bit 192khz 24-bit ?? Dac
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta = 25 C; AVDD, DVDD = 4.75~5.25V)
Note: 17. DFS0/CAD0, CKS1/CAD1 and P/S pins have internal pull-down or pull-up devices, nominally 100k .
(Ta = 25 C; AVDD, DVDD = 4.75~5.25V; C
Notes: 18. When the normal/double/quad speed modes are switched, AK4395 should be reset by PDN pin or RSTN bit.
