While they are based on a similar architecture, the PCM1795 and PCM1792A are different.
Looking historically, the PCM1796 and PCM1792 were based on similar designs, but the digital interpolation filter and current segment engine on the PCM1792 are larger and more complex than the 96. (hence it's 9dB better performance)
In 2009, we launched the PCM1795, which used the same analog section (current sources, voltage references etc) as the PCM1796, but with a new digital interpolation filter that could support 32bit data.
It was found that with an equal amount of averaging as a competitors device, that the analog back end in the PCM1796 could actually show analog content at levels equivalent to the 25th bit.
As a consequence, the PCM1795 was born as a potential replacement for the PCM1796.
s3tup also makes a good point, compared to the PCM1792, the PCM1795 is a lower cost product. That has been a strong part of it's success. At 123dB dynamic range, it is still considered an excellent DAC and remains a strong part of our portfolio.
