High performance audio DAC solutions

For more than three decades ESS™ Technology has been on the cutting edge of audio technology. A privately held, fabless semiconductor company, ESS Technology designs and markets high-performance analog and audio devices for mobile, consumer, automotive, and professional audiophile systems. The company was founded in 1984 by Forest Mozer to produce synthetic speech for various devices including the first wave of speech enabled toys and iconic home computer systems, like the Commodore 64. Today ESS Technology is best known for its SABRE series of high- performance audio products.

ESS PRO SABRE Digital to Analog Converters

The ESS PRO SABRE series of Digital-to-Analog Converters (DAC) is targeted at premium audiophile and recording studio equipment. These premium DACs set a new benchmark in high-end audio by offering the industry’s highest dynamic range (DNR) with impressively low levels of total harmonic distortion plus noise (THD+N) in a 32-bit, 8-channel DAC.

All PRO SABRE DACs feature ESS’s patented 32-bit HyperStream DAC technology. The HyperStream architecture is responsible for both the outstanding sound quality of ESS PRO SABRE DACs and the extremely low THD+N. Other 32-Bit 8-Channel DACs, using typical delta-sigma architecture, feature –107 dB THD+N (0.0004%), which when subjected to individual listening tests do not equal the clarity and sound stage of the ES9038PRO. The PRO SABRE series was created to integrate seamlessly with both the existing and future portfolio of ESS headphone amplifiers as well as other audio building block technology.

For serious audiophiles the PRO series provides the most immersive listening experience – bringing music to life. Studio environments can also leverage PRO SABRE DAC industry-leading performance for professional audio workstations and other equipment.

ES9311 Dual low-Noise, low-dropout regulator

The ES9311 is the industry’s first low-noise, low-dropout regulator designed specifically for high-performance audio systems. It is optimized for high resolution audio (HRA) thanks to its revolutionary dual regulator architecture. This innovative architecture contains series-voltage and shunt-voltage elements, eliminating the need for output decoupling capacitors – an industry first in audio system design. The ES9311 provides the extremely low-noise outputs that are necessary for driving the reference inputs of audio converters and offers significant value-add for audio system designers.
