unsurpassed  tracking  performance,

 Use Burr Brown from TI 

PCM1798, 24-Bit/ 192 KHz Sampling Advanced Segment 

D/A Converter architecture

 to achieve 

excellent dynamic performance (123dB 

typically)

 and improved tolerance to clock jitter. The DAC offers excellent 

SNR up to 

123dB typical

, excellent 

THD+N down to 0.0005% typical

 and with excellent 

8x 

Over-sampling

 Digital Filter giving 

Pass-Band Ripple down to + - 0.002dB

.  The 

DAC can handle
