AKD4628A-B Datasheet, PDF (2/44 Pages) Asahi Kasei Microsystems – single chip CODEC that includes two channels of ADC and eight channels of DAC.

[AKD4628A-B]
Operation sequence
(1) Set up the power supply lines.
[+12V] (Orange jack) = +12 ∼ +15V
[-12V] (Blue jack) = -12 ∼ -15V
[AGND] (Black jack) = 0V
[DGND] (Black jack) = 0V
Each supply line should be distributed from the power supply unit.
±12V are supplied to analog interface.
+12V is regulated to +5V and +3.3V by regulators (T1, T2).
+5V is supplied to digital interface, AK4628A and TVDD of AK4112B.
+3.3V is supplied to AVDD and DVDD of AK4112B and TVDD of AK4628A.
(2) Set up the evaluation mode and jumper pins. (See p.6.)
(3) Power on.
The AK4628A, AK4112B and AK4103A should be reset once bringing PDN (SW1) “L” upon power-up.
(4) Set up software.
The control mode of AK4628A and AK4112B is fixed to “serial”.
The AKD4628A-B can be controlled via the printer port (parallel port) of IBM-AT
compatible PC. Connect PORT1 (uP-I/F) with PC by 10-line flat cable
packed with the AKD4628A-B.
