ak4682 AKM Semiconductor, Inc., ak4682 Datasheet - Page 9

• Manufacturer Part Number: ak4682
• Description: Multi-channel Codec With 2vrms Stereo Selector
• Manufacturer: AKM Semiconductor, Inc.

(Ta=-20°C ~+85°C; TVDD=2.7 ~ 5.25V; DVDD1, DVDD2, AVDD1, AVDD2=4.75 ~ 5.25V; PVDD=8.5∼12.6V)
(Ta=-20°C ~+85°C; TVDD=2.7 ~ 5.25V; DVDD1, DVDD2, AVDD1, AVDD2=4.75 ~ 5.25V; PVDD=8.5∼12.6V; C
20pF (except for SDA pin), Cb=400pF(SDA pin))
Note: 10 MCLKB supports only the normal mode (256fsn, 384fsn, 512fsn, 768fsn).
Note: 11 The AK4682 can be reset by bringing the PDN pin = “L”.
Note: 12 These cycles are the number of LRCKB rising from PDN rising.
