AKD4551 Datasheet, PDF (6/17 Pages) Asahi Kasei Microsystems – EVALUATION BOARD REV.C FOR AK4551

ASAHI KASEI
[AKD4551]
n DIP switch set up
Upper-side is “ON” (“H”) and lower-side is “OFF” (“L”).
[SW3]: Sets the C-bit of CS8402. (Default is the consumer mode.)
This set up does not affect the evaluation of the AK4551. In case of using DIT, need to set it up correctly.
For more detailed configurations, please refer to the CS8402 data sheet.
