32-Bit Stereo Mobile Audio DAC

The ES9028Q2M SABRE32 Reference DAC is a very high-performance, 32-bit, Stereo audio D/A converter designed for; audiophile-grade portable applications such as mobile phones, 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 Eliminator, the ES9028Q2M SABRE32 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.

The ES9028Q2M SABRE32 Reference DAC’s 32-bit HyperStream™ architecture handles up to 32-bit 384kHz PCM data via I2S, 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.

The ES9028Q2M SABRE32 Reference DAC sets the standard, SABRE SOUNDTM, 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.
