Note:

1. The evaluation board is shipped from the factory in the Professional mode. Changing switch 3 to

open places the CS8402 in Consumer mode; however, the hardware is not set up for consumer

mode. To modify the hardware for Consumer mode, change R19 to 374

Ω and add R20 at 90.9Ω.

Then, as shown in the figure below, cut the trace connecting TXN to the transformer, and connect

the transformer side to the ground hole provided. For a full explanation of the consumer hardware

interface, see the CS8402 data sheet, Appendix B.
