ES9822 PRO 32-bit High-Performance 2-Channel ADC Product Brief Analog Reinvented The Sabre ES9822 PRO is the worlds highest performance 32-bit analog-to-digital (A/D) converter targeted for professional audio applications such as recording systems, mixer consoles and digital audio workstations (DAW), test equipment, instruments, audio processors, digital turntables, and consumer applications. The ES9822 PRO has 2 integrated ADCs which use the ESS proprietary 32-Hypersteam II ADC Architecture, which delivers unprecedented audio sound quality and specifications, including a DNR of +127dB in mono mode and a DNR of +124dB, THD+N of -117dB in 2 channel mode. The SABRE ADC supports synchronous SPDIF, I2S master/slave, or native DSD output. For the most demanding audio enthusiast, the ES9822 PRO is capable of outputting RAW data, allowing the user to apply their own custom handling of the data. The ES9822 PRO comes in a small compact package and consumes less than 170mW. The ES9822 is able to use preprogramed filter coefficients to match perfectly with the SABRE PRO Series of DACs including the ES9038PRO. These complimentary filters allow for analog-digital-analog processing with the upmost audio fidelity and minimized time-domain smearing. The Audio Signal Processor (ASP) integrated in the ADC allows for custom filtering such as RIAA presets to be implemented in the ADC, eliminating the need for re-processing later in the signal path. The ES9822 PRO has an Ultra-Low Noise Floor Bandwidth of 200kHz. This bandwidth is up to 10 times wider than the competition, enabling higher resolution at higher sample rates. 3 FEATURE DESCRIPTION +124dB DNR per channel +127dB DNR in mono mode Unprecedented dynamic range and ultra-low distortion -117dB THD+N per channel -118dB THD+N in mono mode High Sample Rates Up to PCM 768kHz Up to DSD512 s Audio Signal Processors (ASP) Available for custom FIR filters for any applications Multiple Output formats available PCM, TDM, DSD, S/PDIF, RAW 8 presets, and programmable filter coefficients for custom sound signature Customizable filter characteristics 2 audio signal processors for custom filter architectures and analog/digital mixing I2C or SPI interface control Configured by microcontroller or other serial interface source Integrated low noise ADC reference regulators Reduced BOM cost, PCB area and improved DNR.
