Data is sourced from manufacturers. Comparisons should take into account the differences in how they test and rate parts. Full data sheets should be consulted before final conclusions are drawn. Follow links to manufacturer's sites above to down load full data sheets.

Notes:

(1) Single channel device.

(2) Uses external Over Sampling filter or DSP filter.

(3) Differential outputs.

(4) Better specification is for 48k sample rate, poorer number is at 96k.

(5) Accepts 24 bit sample words.

(6) Rated at 16x over sampling filter for 48k sample rates, assumes 8x OS for 96k.

(7) Crystal rates as 48k part, selected parts work at 96k and are being used as such by some manufacturers.

(8) Preliminary data for new part, full data sheet not yet available.

Color code:

Blue = Standard setting 44k/16 bit parts included for comparison.

Green = Standard setting 96k/24 bit parts specifications meeting or exceeding 44/16 standards.

Red = Specifications below best 44k/16 bit standards.
