ESS Technology Introduces New Stereo High Performance CODEC

< Newsroom | Posted: Tuesday January 23, 2024

The newest generation of SABRE high performance DACs and ADCs are now incorporated together in the new CODEC

January 23, 2024 – San Jose, California – ESS Technology, Inc., the industry leader in audio semiconductor devices, today introduces a new SABRE® CODEC that integrates stereo analog and digital channels with outstanding performance.

The ES9290 is a synchronous CODEC incorporating both stereo ADCs and DACs that provide ultra-low noise conversion with a dynamic range (DNR) of +116dB/+116dB, THD+N is rated at -110dB/-108dB (DAC/ADC respectively) per channel.

The SABRE CODEC integrates many BOM simplification and reduction features.

  • Programmable gain amplifiers (PGAs) with a gain of up to +30dB
  • 2Vrms Line Driver Buffers
  • Custom pre-programmed filters that are complementary to both ADC & DAC
  • Digital Full Biquad (DBQ) filter that is fully customizable to implement any Full Biquad, with many preset options such as 80Hz/120Hz high pass, RIAA de-emphasis and pre-emphasis filters
  • An analog phase locked loop (APLL) reduces BOM requirements for simplification
  • A programmable microphone (MIC)BIAS for analog microphone support
  • ADC and DAC mixing
  • Independent wide Digital volume control including up to +42dB of digital gain
  • Digital and Analog Low Noise Regulators to maximize DAC and ADC performance
  • Internal/External clock sync setting to the TDM interface

An incorporated Direct Monitoring mode will allow to listen to the analog input signal with very low latency through the direct path from the ADC/PGA to the DAC/line driver interface while having the ability to record the input signal.

The ES9290 included PGAs with a gain of up to +30dB in +3dB steps and Line Drivers reduce bill of materials by providing front-end and back-end circuits for gain and output levels requirements.

The ESS patented Hyperstream® IV architecture incorporated in the ES9290 provides the SABRE legendary sound quality which further improves audio performance while consuming lower power compared to previous generations providing a full and rewarding listening experience.

The ES9290 supports multiple I/O formats including TDM, TDM Daisy Chain, I2S, LJ, RJ while supporting up to 768kHz sample rate using 64FS mode.

The control interface can be programmed using multiple input methods including I2C, SPI, and a hardware mode (HW) for ease of programmability.

The SABRE CODEC is well suited for Professional Audio Interfaces, Live stream media, High-quality microphones, and professional DAW (Digital Audio Workstation) Audio Recording.

“ESS has been the highest performance and market leader on DACs and ADCs. We’ve combined them in the best of class performance stereo CODEC with the lowest BOM and ease of use features for audio system designers.” said Robert Wong VP of ESS Worldwide Sales and Marketing.

The ES9290 is available in a 40 pin 5mm x 5mm QFN package.

Evaluation boards, reference designs, and samples are available. For more information, please contact your local ESS Representative or distributor.
