ESS Technology, Inc., the industry leader in high-performance audio semiconductors, today unveiled three new flagship SABRE® PRO SMART Analog-to-Digital Converters (ADCs) based on ESS’s patented Hyperstream® IV ADC architecture that set a new standard for performance in both professional and consumer audio applications.
The new ES9823MPRO and ES9823PRO are advanced 2-channel SMART ADCs offering class-leading audio performance with a dynamic range (DNR) of +128 dB and a total harmonic distortion plus noise (THD+N) of -117 dB. This represents the highest per-channel specification currently available in the industry, with an impressive +130 dB DNR in mono mode.
Joining them is the ES9843PRO, a 4-channel SMART ADC delivering exceptional fidelity with a DNR of +125 dB and -116 dB THD+N per channel in 4-channel mode.
All three new SABRE® PRO ADCs are powered by ESS’s second-generation Audio Signal Processor (ASP2), providing unparalleled integration capabilities. ASP2 supports custom audio processing including multi-band parametric EQs, mixers, stereo widening, audio expansion and compression, RIAA pre-emphasis, crossover filters, dynamic range compression (DRC), automatic gain leveling (AGL), and more. This integration minimizes or eliminates the need for external DSPs, streamlining design, reducing software complexity, and lowering bill-of-material (BOM) costs.
To further simplify development, the new ADCs are compatible with ESS’s Sabre Intelligence Studio (SI Studio), a user-friendly programming interface that accelerates design flow and shortens time-to-market.
The ES9823MPRO is also the first ADC in the world to integrate FOQUS by MQA Labs® —a revolutionary decimation filter with a minimum-phase response engineered to stay below human perceptual thresholds. Its single dithered quantization step and low-complexity architecture make FOQUS the most transparent decimation technology available today.
“FOQUS represents a major step forward in our mission to help people perfectly capture sound digitally,” said Al Wood, Director of Engineering at Lenbrook’s MQA Labs. “ESS has long been a leader in high-performance audio. We’re confident that the ES9823MPRO, with FOQUS built-in, will set a new benchmark in analog-to-digital conversion.”
All three devices support a comprehensive set of digital output formats, including S/PDIF encoding, I²S master/slave, TDM, PDM, DSD, DoP, and RAW. They also feature PDM microphone input support and built-in digital filtering with pre-programmed and customizable filter coefficients, including DC blocking options. Interfaces include both I²C and SPI, with a master SPI port to connect an external FLASH device for rapid ASP2 configuration.
Using two ES9823(M)PRO devices in ESS Proprietary multi-chip mixing configuration, designers can achieve dynamic range performance exceeding 136dB.
The new devices are drop-in compatible with previous flagship models—ES9822PRO and ES9842PRO—and are available in a compact, low-pin-count 5×5 mm 40-pin QFN package.
