I saw the 35 page data sheet of ESS Sabre ES9012 / ES9018 Reference 32-bit Audio DAC Datasheet.Unlike many other DAC data sheets, there is no ripple spec. Does anyone know why?
FIY, ripple specs on other DAC data sheets are below.WM8742: 0.000057 dB (filter 1, 32/44.1/48kHz)
CS4396: + - 0.0001 dB (single speed mode)
CS4398: no numerical value, but graphs are given.
PCM1796: + - 0.0002 dB (sharp roll off)
PCM1795: + - 0.0002 dB (sharp roll off)
PCM1792: + - 0.00001 dB (sharp roll off)
PCM2902: + - 0.1 dB (This chip is the AD/DA/USB-interface chip in Behringer UCA202, Behringer Xenix 302USB)
AK4490: + - 0.005 dB

As above it's a largely meaningless number, 75% of a DAC's performance is due to competent implementation.
Not because of the DAC chip utilised.
While I don't have a copy of the ESS datasheet, I would guess that they simply don't deem the digital filter's in-band frequency domain ripple spec. to be of consequence. This would be understandable, given the typically extremely small magnitude of such ripple. That said, I do note that a small number of DAC designers feel that the in-band ripple is indicative a some audible processing error phenomena.
