In Reply to: Then it would cease to be a Benchmark DAC1 but...... posted by rfbrw on May 8, 2005 at 12:13:39:
The AD1853 includes a digital filter with 8x oversampling so you wouldn't use it if you wanted to change the digital filters, but it isn't designed for a specific input rate like 4Fs. It's compatible with sample rates from 32K to 192K. The DAC1 precedes it with an upsampling digital filter set to 110 KHz which is a little below 3 Fs. But you're right in that the changes required would be too extensive and he'd be better starting with a design that was closer to his own philosophy.
