ES9028PRO
HypersStream II Audio DAC
Using the critically acclaimed ESS' patented HyperStream
ES9028PRO 32-Bit Audio DAC delivers an unprecedented DNR of up to 135dB in mono mode and THD+N of –120dB, the
industry's highest performance level that will satisfy the needs of the most demanding audio applications.
The ES9028PRO handles up to 32-bit 768kHz PCM, DSD256 via DoP and native DSD1024 data in master or slave timing
modes. Custom sound signature is supported via a fully programmable FIR filter with 7 presets. Residual distortion from
suboptimal PCB components and layout can be minimized using ES9028PRO's unique THD compensation circuit, while
chip-to-chip gain variation is minimized via a built-in auto gain calibration circuit.
The SABRE ES9028PRO sets the standard for HD audio performance, SABRE SOUND
®
64-eTQFP package for today's most demanding digital-audio applications.
