fastest pure-PCM DACs

el`Ol · 23rd February 2008, 04:36 AM

Hello all!

How fast are the fastest pure PCM-DACs,
for 8 Bit, 12 Bit, 16 Bit, 20 Bit, 24 Bit?

192kHz?

24bit : )))))))))) , for real : 16 bit 600 MSPS

Are these AD beasts all pure PCM?
And is highspeed >16bit not possible, or is there just no market?

I used to check if TI wantsto release some new r2r with SiCr thin film and I out , but nothing yet.

pcm1704 is already high speed capable of 16x os

The PCM1704 and the WM8740 (and probably others) have 8xFs modes for use with an external digital filter. In 8x mode they accept 768kHz sample rate, 24-bit samples. Neither chip is upsampling in this mode; that is assumed to have been done by the external filter, like the DF1704.

I remember the Wadia Power DAC that reached 2.8Mhz with eight of them driven phase-shifted many years ago. Any progress so far? And what about ADCs?

slaughters the newer versions....

at least in my humble opinion

The PCM1704 has no interrnal filter.
