CS4398 Evaluation Board CDB4398

Saturday, November 8th, 2003

CS4398 is a voltage output 24bit DAC.  I have tried to modify this DAC evaluation board using Audio transformer Lundahl LL7902 as the IV filter.  The performance is not much different from the original design using op-amps.  Overall this DAC do not sound great!

I cannot find any picture yet and I shall post it here when available.

TDA1543 DAC

This DAC copy the design of Audio Note DAC using 4 pcs TDA1543 IC.  The overall performance is worse than TDA1541 due to limited performance of the DAC IC itself.
