Astute Group offers the ES9290Q stereo high-performance CODEC from ESS Technology, incorporating both ADCs and DACs with ultra-low noise conversion, making it perfect for capturing and reproducing pristine audio.

The ES9290Q is a synchronous CODEC with an incredible dynamic range (DNR) of +116dB/+116dB, THD+N is rated at -110dB/-108dB (DAC/ADC respectively) per channel.

“The ES9290Q represents a significant leap forward in stereo CODEC technology,” said Astute Group’s Dave Everitt​​​​, Technical BDM (Audio) ESS European Product Manager. “Its exceptional audio performance and BOM-friendly features make it an ideal choice for a wide range of Pro-Audio applications.

“What is most amazing about the ES9290Q is the mainstream performance from a Codec as well as Direct Monitoring (<10 samples from the ADC to the DAC), LDOs, and PLLs on an integrated chip.”

“We’re coming to Munich High-End Society, 9-12th May, 2014, to support ESS Technology and their legions of European fans and customers. If you’re going to be at the show, please contact me at [email protected] to set up a meeting.”

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

• 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 customisable to implement any Full Biquad, with many preset options such as 80Hz/120Hz high pass, RIAA de-emphasis, and pre-emphasis filters
• An analogue phase-locked loop (APLL) reduces BOM requirements for simplification
• A programmable microphone (MIC)BIAS for analogue microphone support
• ADC and DAC mixing
• Independent wide Digital volume control including up to +42dB of digital gain
• Digital and Analogue Low Noise Regulators to maximize DAC and ADC performance
• Internal/External clock sync setting to the TDM interface

“ESS Technology 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.

Need help to understand ESS Technology part numbers? In this case, ES9290Q = ES is ESS, 92 is CODEC (COder DECoder .. that is it has an ADC and DAC function, in this case it is 2-ch ADC and 2-ch DAC) and 90 is the variant, Q is QFN package.
