ES9022 - ESS’ new Stereo Sabre DAC with integrated 2Vrms driver and 112dB dynamic range from Ismosys
Ismosyshas launched the ES9022 Sabre Premier Stereo DAC with 2Vrms driver from ESS Technology, an addition to the latter company’s Vista family of high-definition audio-visual products. This is supported by two low cost evaluation boards which will enable A/V design engineers to explore the possibilities offered by the new chip.
The ES9022 combines the highly acclaimed Sabre™ DAC and a high performance 2Vrms output driver into the ideal D/A converter for line-level output applications such as Blu-ray players, CD/DVD players, set-top boxes, digital TVs and game consoles. With a patented Hyperstream architecture and a patented Time Domain Jitter Eliminator, the ES9022 supports 24-bit conversion with up to 192kHz sampling rate and delivers jitter-free studio quality audio with 112dB of dynamic range, setting a new performance benchmark by outperforming all 3.3V powered D/A converters with 2Vrms drivers in the market.
The ES9022 has integrated charge pump and operates from a single 3.3V supply to drive a ground-centered 2Vrms output. The result is the lowest system cost by eliminating the need for an output op-amp filter, DC-blocking capacitors, a mute circuit or multi-rail power supplies. In addition, the ES9022 output level is adjustable via an external resistor, allowing custom output levels below 2Vrms. Pop-noise is eliminated through comprehensive suppression on power up/down, mute and reset.
Robert Wong, vice-president of marketing and worldwide sales for ESS Technology, said, “The ES9022 Sabre™ Premier DAC is the highest performance product of its class at 2Vrms line level with a single 3.3V power supply. With bill of materials reduced to just a few passive components externally, audiophile sound and quality are now accessible and affordable to consumers.”
