... Digital Audio Interface http://www.cirrus.com Description The CDB4350 evaluation board is an excellent platform for quickly evaluating the CS4350 24-bit, 24-pin, stereo D/A converter. Evaluation requires an analog signal an- alyzer, a digital signal source for controlling the CS4350 (only required for Control Port Mode), and a power supply ...

... CS4350 as possible. Extensive use of ground plane fill in the evaluation board yields large reductions in ra- diated noise. 8. ANALOG OUTPUT FILTERING The analog output on the CDB4350 has been designed according to the CS4350 datasheet. This output circuit in- cludes an active 2-pole, 50 kHz filter which utilizes the multiple-feedback topology and a passive output filter. 4 ...
