• Manufacturer Part Number: AK4103A_09
• Description: 192kHz 24-Bit DIT
• Manufacturer: AKM [Asahi Kasei Microsystems]

Note 1. Internal pull-up and pull-down resistors are connected on-chip. The value of the resistors is 43kΩ (typ).
Note 2. All input pins except internal pull-down/pull-up pins should not be left floating.
