CONFIDENTIAL ES9028Q2M 32-Bit Stereo Low Power Audio DAC Datasheet Analog Reinvented 32 The ES9028Q2M SABRE Reference DAC is a very high-performance, 32-bit, Stereo audio D/A converter designed for audiophile-grade portable power sensitive applications such as digital music players, Blu-ray players, audio pre-amplifiers and A/V receivers, and professional applications such as recording systems, mixer consoles and digital audio workstations. Using the critically acclaimed ESS patented 32-bit HyperStream DAC architecture and Time Domain Jitter 32 Eliminator, the ES9028Q2M SABRE Reference DAC delivers a DNR of up to 129dB and THD+N of 120dB, a performance level that will satisfy the most demanding audio enthusiasts. 32 The ES9028Q2M SABRE Reference DACs 32-bit HyperStream architecture handles up to 32-bit 384kHz 2 PCM data via I S, DSD-22.6MHz data as well as a mono mode for highest performance applications. Both synchronous and ASRC (asynchronous sample rate conversion) modes are supported. 32 TM The ES9028Q2M SABRE Reference DAC sets the standard, SABRE SOUND , for HD audio performance, typically consumes 83mW in normal operation mode (< 1mW in standby mode), and comes in an easy-to-use, 32-QFN package.
