Overview: Analog Reinvented ES9841
4 Channel High Performance ADC Product Datasheet The SABRE ES9841 is a synchronous, high-performance 4-channel analog-to-digital (ADC) converter that targets professional and consumer applications with outstanding audio quality and low bill-of-materials. The ES9841 incorporates 4 ADCs using ESS’ patented Hyperstream® IV architecture which delivers unprecedented audio sound quality and specification of a True DNR of +122dB and a THD+N of -115dB per channel in 4 channel mode and a True DNR of +125dB in stereo mode. The SABRE® ADC supports S/PDIF encoding, I²S master/slave, TDM outputs and PDM microphone inputs. The ES9841 can be controlled by software (I²C /SPI slave) or hardware mode (HW) to reduce programming complexity. A Master SPI port is also integrated allowing for external control of other devices. The ES9841 has an integrated patented Analog PLL which eliminates the requirement for an external oscillator with no loss in specified performance. Built-in pre-programmed digital filters, including a DC blocking filter, allowing for custom sound and latency preferences. The ES9841 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. The ES9841 sets the standard for recording capabilities with regards to audio performance and customization, in a form factor that is required for the most demanding recording applications.
