ES9840 32-bit High-Performance 4-Channel ADC Product Brief Analog Reinvented The Sabre ES9840 is a 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 Sabre ES9840 has 4 integrated ADCs which use the ESS proprietary 32-Hypersteam II ADC Architecture, which delivers unprecedented audio sound quality and specifications, including a DNR of +118dB in mono mode and a DNR of +116dB, THD+N of 108dB in 4 channel mode. The SABRE ADC supports synchronous S/PDIF, I2S master/slave, or native DSD output. The ES9840 comes in a small compact package and consumes less than 155mW 48kHz The ES9840 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 ES9840 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.
