ESS Technology Launches Advanced ES9219 Headphone SoC for Mobile Devices

Just a few short days after launching its new Sabre Smart Power-Amplifier (SPA), a new-generation device designed to boost the audio quality and efficiency of phones, wireless speakers, and even the smallest connected wearable devices, ESS Technology announced the ES9219, the 3rd generation of Sabre DAC headphone System-on-Chip (SoC) solutions for mobile devices. The ES9219 Headphone SoC with 32-bit, QUAD DAC Technology and 2Vrms output adds crosstalk reduction and THD compensation while reducing BOM size and cost.

The ES9219 streamlines the integration with headset audio systems by integrating jack-sensing with ESS’s patented output bypass switching, eliminating the need for external components. According to the company, this new generation Sabre DAC provides exceptional audio performance, with +130dB SNR and +121dB DNR, while providing a better overall cost solution to the customers. “The ES9219 is the ideal choice for mobile device makers who want a highly integrated solution that doesn’t compromise on audio performance or sound quality,” says Robert Wong – Vice President of Worldwide Sales and Marketing for ESS.

The ES9219 also integrates an audiophile PLL and LDO, eliminating the need for external regulators and crystal to support low noise across the full range audio sampling rates. Combined with the 42 ball CSP package, the result is an application that is significantly smaller than competing solutions.

The ES9219 features a brand-new proprietary THD solution to significantly reduce variation across devices without the need for manual custom tuning achieving -114 dB THD+N at 1.0Vrms into 100k Ohm. Additionally, to further improve cross-talk, ES9219 has a proprietary cross-talk reduction solution, resulting in a crosstalk free listening experience for the user.

This new generation of SoC can also support MQA as well as an extensive range of other high-resolution and lossless audio formats, including 32-bit 384 kHz PCM, DSD512, DoP, FLAC, ALAC, AIFF and WAV. MQA hardware rendering is a great fit for devices that can use software decoders, such as the ones built into media-streaming applications.

“This highly-integrated solution with the new benchmark on audio performance is an ideal cost-effective solution,” adds Robert Wong. “Using this new Sabre DAC headphone System-on-Chip (SoC) solution, the mobile devices can now provide differentiating sound quality and music-streaming features to their customers.”
