ES9842 PRO 32-bit High-Performance 4-Channel ADC Product Brief Analog Reinvented The Sabre ES9842 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 ES9842 PRO has 4 integrated ADCs which use the ESS proprietary Hyperstream II Architecture, which delivers unprecedented audio sound quality and specifications, including a DNR of 128dB in mono mode and a DNR of +122dB, THD+N of 116dB in 4 channel mode. The SABRE ADC supports synchronous SPDIF, I2S master/slave, or native DSD output. For the most demanding audio enthusiast, the ES9842 PRO is capable of outputting RAW data, allowing the user to apply their own custom handling of the data. The ES9842 PRO comes in a small compact package and consumes less than 210mW. The ES9842 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 ES9842 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.
