ak4342 AKM Semiconductor, Inc., ak4342 Datasheet - Page 11

• Manufacturer Part Number: ak4342
• Description: 24-bit Stereo Dac With Hp-amp & 2v Line-out
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta=25°C; AVDD, DVDD, HVDD, PVDD=2.7 ∼ 3.6V; TVDD=1.6 ∼ 3.6V)
Note 25. Refer to “Serial Data Interface”.
Note 26. When BCKP bit is set to “0”, BICK rising edge must not occur at the same time as LRCK edge.
Note 27. When BCKP bit is set to “1”, BICK falling edge must not occur at the same time as LRCK edge.
Note 28. The AK4342 can be reset by bringing PDN pin = “L” to “H” only upon power up.
