• Manufacturer Part Number: ak4126
• Description: 6ch 192khz / 24-bit Asynchronous Src
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Note: SDTO shows SDTO1, SDTO2 and SDTO3.
The AK4126 has 4-channel mode to reduce power supply current when using four channels in six channels. When PM pin
is set to “H”, four channels (SDTI1
MS0544-E-00
4-channel Mode
SDTO3) are powered-down (SDTO3 outputs “L”.).
