ESS Technology Announces the World’s Highest Performance Audio Analog-to-Digital Converter with a Staggering +128dB of Dynamic Range

New SABRE PRO & SABRE Analog-to-Digital Converters (ADC) set the new benchmark for audio performance with unmatched specifications and the highest sample rate available in the market

San Jose, California - ESS Technology, the industry leader in audio semiconductor devices, today announced their new series of SABRE PRO and SABRE ADCs with an Ultra Low Noise Floor Bandwidth of 200kHz. The Ultra Low Noise Floor Bandwidth is up to 10 times wider than the competition, enabling higher resolution at higher sample rates.

The ES9842 PRO provides 4 channels of ADC with a DNR of 122dB and 116dB of THD+N, the ES9822 PRO is a 2 channel ADC, with a DNR of 125dB and 117dB of THD+N, achieving the best per channel specification of any part on the market. When the ES9842 PRO’s 4 channels operate in parallel, as a mono channel ADC, they provide +128dB of dynamic range, a performance mark that is the best in the industry today. 

The ES9840 & ES9820 provides 4 & 2 channels of ADC with a DNR of 116dB, and 108dB of THD+N.

The new SABRE PRO ADC offers incredibly fast sample rates, handling PCM sampling rates up to 768 kHz and DSD rates up to DSD512.  Utilizing the optional RAW data output or custom Serial PCM interfaces, sample rates up to 24MHz are supported when combined with an FPGA. This allows for a highly customizable solution for the most demanding of systems.

The new SABRE PRO ADCs are ideally matched with existing SABRE PRO DACs such as the ES9038PRO.  Together, these parts make the most acoustically transparent signal processing loop available. Outstanding acoustical performance is achieved with the use of pre-programed complimentary filters that are ideally matched to preserve the time-domain performance, and hence best imaging and most accurate signal preservation possible.

The SABRE PRO ADCs also uses ESS’ patented HyperStream-II modulator that gives 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.   Hyperstream-II technology also allows SABRE PRO ADCs to have a flat noise floor of 200kHz with more than 10dB lower distortion compared to other competing devices.

These powerful, cutting edge features make system design easier and more efficient.  Features including a built-in Audio Signal Processor (ASP) that allow for 8 biquad filters that can be customized or used as RIAA filters without adding external components.  The ADCs feature an inter-channel gain mismatch of less than 0.5 dB, eliminating the need for external balancing and hand-trimming.   The parts feature a programmable digital high-pass filter to remove DC offset from the input, as well as S/PDIF output.  

This exceptional high level of performance comes while operating at very low power consumption.   The parts operate at less than 52mW per channel, lower than many competing parts that have significantly worse audio performance. 

The ES9840 & ES9820 SABRE ADCs have many of the features of the SABRE PRO series but are a more cost effective solution when absolute maximum performance is not required.

These new SABRE PRO and SABRE ADCs are ideal for the most demanding of equipment, including audio mixing consoles, high-performance Microphone Preamplifiers, Audiophile equipment, samplers, audio processors and test equipment.

All devices are available in a 40 pin QFN package keeping the board space to a minimum.  In addition, a 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
