ASAHI KASEI
AKD4589-B is an evaluation board for AK4589, a single chip 24bit CODEC that has two channels of ADC
and eight channels of DAC with internal DIR, DIT. It has interfaces with evaluation boards for A/D
converter and D/A converter of AKM's and make easy to evaluate AK4589. It also has the digital audio
interface and can achieve the interface with digital audio systems via opt-connector or BNC connector.

  • Page 6 Serial Control AK4589 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect printer port (parallel port) of PC and PORT1(uP-I/F) of AKD4589-B by 10 wire flat cable(packed with AKD4589-B). Take care of the direction of 10 pin connector and 10 pin header.

  • Page 7: Analog Inputs

    AK4589 device are nominally 3.1Vpp@5V.But,for the resister division,the value which analog input level of Evaluation Board is devided by two becomes to analog input level of AK4589 device on the AKD4589-B. So, input ranges of AKD4589-B becomes to 6.2Vpp@5V,twice of the value in the case of AK4589 device. Input range of AK4589 device is proportional to VREFH (3.1=0.62 x VREFH).

  • Page 8: Analog Outputs

    BNC connector J2 (LOUT1), J1 (ROUT1), J4 (LOUT2), J3 (ROUT2), J6 (LOUT3), J5 (ROUT3) J8 (LOUT4) ,J7 (ROUT4) are used for analog outputs on the AKD4589-B. Analog outputs are single-ended and output ranges of each channels are nominally ±3.82Vpp@5V. (Analog outputs of AK4589 device are differencial and output ranges of each channels are nominally ±2.7Vpp@5V.But, input ranges of AKD4589-B becomes to ±3.82Vpp@5V,about...
