The new SABRE ES9033Q DAC simplifies stereo line level setups with best-in-class performance in one small package

San Jose, California – ESS Technology, the industry leader in audio semiconductor devices, today announced their newest addition to the SABRE® audio series of DACs, the ES9033Q, a 32 bit, 2 channel DAC with built-in 2Vrms, ground-centered line drivers.

The ES9033Q is a 2 channel D/A converter with a DNR of 122+dB A-weighted with DRE and -108dB of THD+N per channel.

The ES9033Q has a combination of ESS’ legendary SABRE DACs with a performance matched 2Vrms line driver output stage resulting in an optimum system performance.  In addition, system designers can save on the total bill-of-materials (BOM), board space and power consumption by taking advantage of the ES9033Q’s built-in phase lock loop (PLL), eliminating the need for an external crystal or oscillator.  Also, the built-in 2Vrms, ground-centered line drivers eliminate the need for external amplifiers required by other DACs.

The ES9033Q can function at high input sample rates, handling PCM sampling rates up to 768 kHz and DSD rates up to DSD512, as well as TDM and DoP formats.

The ES9033Q can be programmed using various input methods. I2C, SPI, and hardware modes are available.

Outstanding acoustical performance is achieved with the use of 8 pre-programmed upsampling filters that are designed to preserve the time-domain response while providing the best imaging and accurate signal preservation possible. A stereo de-emphasis filter can also be set if required.

The ES9033Q also has ESS’ proprietary HyperStream® II modulator that gives ESS’ SABRE DACs their legendary sound quality.  HyperStream II modulation allows for timing jitter to be pushed out of the audio range so the resulting soundstage is pure and consistent.

The new ES9033Q can be used in receivers, stereo and multi-channel setups, other audio equipment including pro audio gear, audiophile equipment, samplers, and audio processors.

The ES9033Q is available in a 28 pin QFN package to minimize the board space.  Full evaluation board and reference design are available.  For more information, please contact your local ESS Representative.  More details can be found at http://www.esstech.com.
