ASAHI KASEI
[AKD4588]
„ Analog Inputs
Analog inputs use J10 (LIN) and J9 (RIN) the analog inputs are single-ended. Each channel signal range is
nominally 3.1Vpp@5V. It is proportional to VREFH (Vin=0.6 x VREFH). VREFH is connected to AVDD on the
AKD4588.
„ Analog Outputs
J2 (LOUT1), J1 (ROUT1), J4 (LOUT2), J3 (ROUT2), J6 (LOUT3), J5 (ROUT3) J8 (LOUT4) and J7 (ROUT4) are
used for analog outputs. The analog outputs are single-ended. Each channel signal range is nominally 3.0Vpp@5V.
It is proportional to VREFH (Vin= 0.6 x VREFH). VREFH is connected to AVDD on the AKD4588.
„ Digital Inputs
Toslink (TORX176: PORT3) or BNC connector (J12) is used for digital inputs. When Toslink (TORX176: PORT3)
is used, JP3 (RX0) set “OPT” side. When BNC connector (J12) is used, JP3 (RX0) set “BNC” side.
„ Digital Outputs
Digital outputs use Toslink (TOTX176: PORT2), BNC connector (J11). When Toslink (PORT2) is used for TX1,
JP2 (TX1) set “OPT” side. When BNC connector (J11) is used, JP2 (TX1) set “BNC” side.
„ Operation sequence

Table 1 Set up of power supply lines
Each supply line should be distributed from the power supply unit.
2) Evaluation Mode
(1) Evaluation of DAC part used internal DIR
(2) Evaluation of ADC part used internal DIT
(See the followings)
3) Set-up the evaluation modes, jumper pins and DIP switches. (See the followings.)
4) Power on
The AK4588 should be reset once bringing SW1 (PDN) “L” upon power-up.
