CONFIDENTIAL ADVANCE INFORMATION ES9028PRO 32-Bit HyperStream II Analog Reinvented 8-Channel Audio DAC The SABRE ES9028PRO HyperStream II 8-channel audio DAC is a high performance 32-bit solution designed for Audiophile and Studio equipment applications such as SACD players, Blu-ray players, digital preamplifier, A/V receivers, studio consoles and digital audio workstations. 2 Part DNR THD+N 32-bit I S / DoP / DSD Jitter Description Package Number (dB) (dB) DAC / SPDIF Input Reduction SABRE PRO 32-bit 8-ch 64 135 (mono) ES9028PRO 120 Yes Yes Yes HypersStream II Audio DAC eTQFP 129 (8-Ch) Using the critically acclaimed ESS patented HyperStream II architecture and Time Domain Jitter Eliminator, the ES9028PRO 32-Bit Audio DAC delivers an unprecedented DNR of up to 135dB in mono mode and THD+N of 120dB, the industrys 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 ES9028PROs 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 , in a cost-effective, easy-to-use 64-eTQFP package for todays most demanding digital-audio applications.
