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 374Ω 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.
